Eureka! Yes. That's the solution to the blasted thing! The general solution to the equation from hell! Run for your life!
LOL
Like the poor misunderstood horned toad, with its titanium armour piercing spikes, it's not as deadly as it looks. If it can't scare you to death with its frightening appearance and fake spikes, it's totally harmless. The same applies to the quadratic equation.
However, it is a fundamental equation of nature. Many of the most important equations of Newtonian mechanics, relativity theory, statistics, electronics, engineering, physics, etc., etc., etc., reduce to quadratic solutions. You find it just about everywhere you look in nature from atoms to galaxies and everywhere in between.
Analyses of electronic circuit problems often heavily apply quadratic equations.
I don't know any fundamental equation more important to the physical sciences than the humble quadratic equation (peace and blessings be upon it).
Any professional "educator" who says it's not important enough to remember the solution after the exam is dumber than a bucket of ****! Especially if the student who naively believes him is considering a scientific or ********* career.
If you only need to keep knowledge just long enough to pass an exam in school and then promptly forget it, what worthy purpose has education served, other than impressing people with your credentials rather than with the knowledge you left behind, lonely and forgotten, like your former girlfriend v*.0 beta?
What a quadratic equation is about
You have probably noticed that most quadratic solutions have a dual solution or two values of X that equally satisfy the equation. The reason that there are two solutions is simply because a quadratic equation generally describes a parabolic curve when plotted on a graph (but there are special exceptions).
If you were to draw a straight line so that it cuts through the parabola at two different points, those two points are the two solutions of the quadratic equation with respect to the intersecting line. Those two points are where the difference between the coordinates of the line and the coordinates of the parabola equate to zero. In other words, the two solutions are the points where the line and the parabola intersect on the graph.
The general form is:
The line, in this general case, is the X-axis on the graph. The two solutions are where the quadratic curve intersects with it.Code:Ax&#*78; + Bx + C = 0
There are two points where the equation is true.Code:Line - Parabola = 0
I think I'll post a function here to solve general quadratic equations given the A, B, C values as arguments. A day without boring someone to death, is a day wasted!
LOL
Examples of the practical applications of the quadratic equation could fill volumes.
So don't ever let anyone convince you that it's nothing worth learning about - unless you aspire to become a teacher and it becomes your job to make sure that passing tests is more important than actual learning.
Here's a simple quadratic toy for you play with:
I'm thinking of a secret number X
If you square that secret number, you will get exactly the same answer you would get if you simply added * to it.
What is the value of the secret number X?
There are two answers. One is negative, the other is positive. If you add the two answers together, their sum equates to exactly *.
They are not big numbers and are both less than 2.
Hint
The ancient Geeks (or was it ancient Greeks) called the solution of the above problem the 'Golden Ratio'. It is so important a number that even today it is called the 'Divine Proportion' among other glorious Latin titles that would make the Pope swoon with envy - and they even didn't have calculators in those days. In fact, at that time, zero hadn't even been invented yet!
The quadratic equation - not just a good idea - it's the law!

Getting a diploma is an even better way to fake it!
You can copy and paste great music, but when you are asked to play it, then you are exposed!
You can copy and paste great equations, but when you are asked to solve or explain them, then you are exposed!
And so it goes that a genius can convincingly play the fool, but the fool can never convincingly play the genius. The only one he fools is himself.
But being a fool can be profitable. Ask the *-Stooges, my heroes!
Or you can always go into politics. From the political quotes I've seen, clearly, intelligence is not a mandatory requirement.

I think I learned about quadratic equations last year, but knowledge slips away without practice.
Oh I've learned a lot from the internet; just not much that actually has a practical use. I can blurt out random facts to people and get the response "really?" ("yeah, really"), but nothing structured.
Not conventional education. Very non-linear.
Also, music, movies and porn don't help with my studies (take up the majority of my bandwidth).
I guess I know enough in programming to perhaps make a career of it. The thing is, I have a problem with motivation -- I start projects and don't finish them because there are so many distractions and side-projects. See here:
[url]http://www.exoteric.ws/[/url]
My site. I started it in early 2006 (in a totally different form), yet it still isn't anywhere near complete.
Another example is my freelancing. I can earn vast amounts of ***** from it if I put the effort in, but I usually don't.
Next there's school. I have a ton of homework at any given time, and I only usually do whatever seems easiest (and interests me). The rest I throw together on the last night. It's not that it doesn't interest me (or I'm not capable of it); it's simply that there are always things to distract me and change my focus of attention.
Oh, and then there's the small task of trying to get a real job on top of all this.
Everything is fragmented. We need 48-hour days.Code:sudo apt-get install motivation E: Couldn't find package motivation
You seem like a good role-model, Jay. How did you motivate yourself to reach your current stage? Perhaps a distinct lack of internet ...
...
You know you spend too much time on the internet when you think of the menu 'undo' button when you make a mistake.
You know you're addicted to the internet when you try to ctrl+f books and documents, and instinctively move your left hand towards ctrl+z when you fuck up in life.

Motivation - The little voice in the back of my head saying finish it now, and you will be paid for the rest of your life.
Thats my motivation... I create projects that bring in small incomes, maybe $*0 a day. I currently have about 5 projects on the web bringing in $500+ a month. Do you know how much work I do on these projects? NONE. I'm finished and will receive a fixed income for the rest of my life. Not to bad huh? This is my motivation, along with coffee, red bull, and the desire to NOT HAVE to work for the rest of my life. Also, im not greedy. Anyone who helps on these projects gets a fair &#*7; of the income also. In the next two years I plan to have at least 20 sites generating in anywhere from $2000-5000 a month. I'm lazy, I have the best job for lazy people. Work When you want, get paid how much you want.
Now I can spend more time writing useless "Hello World!" programs & cracking Moonbats uncrackable double dutch passwords
Oh yeah, the supercomputer build is still open for Part Donations
IF ANYONE EVER COMES UP WITH ANY SMALL BUSINESS IDEAS AND WOULD LIKE TO WORK WITH SOME SERIOUS PEOPLE LET ME KNOW.

Been to your site and registered. Naturally, HotMail automatically thew the reg email in the junk mail bin & didn't even tell me I had e-mail. IDIOTS!
I don't know if I'm much of a role model. I'm like a ghost. Outside of my immediate family, few people even know I exist.
Most of my education is very non-linear too. I prefer to teach myself. It's faster.
My major motivation is an intense scientific and analytical curiosity to the point of psychosis, or so it seems to some. I can't pass up an opportunity to learn something new once my interest has been piqued, so I slither around the Internet looking for new scientific information constantly.
Natural curiosity is my key. It's a powerful driving force because it is its own reward and feeds on itself. Curiosity doesn't need to be paid to work. ***** doesn't motivate me if I don't like what I'm doing. Greed has minimal influence on me.
I study just about everything, especially science and math, which I merge together with computer programming. Physics, astronomy and practical math (e.g. math you can actually apply to something in the real world) are my main focal interests.
Just about any time I get curious or want to look up something, I use the Internet like my own private library. It's amazing how many new things I've learned over the last *2 years on the net.
The Internet is a dangerous paradox though.
The Internet is one of the best places to find useful information on just about anything you can imagine, while at the same time, the Internet is one of the best places to find bogus information on just about anything you can imagine.
The real art lies in knowing how to tell the difference. That takes a lot of experience and can be treacherous at times.
My sister has used the Internet for nearly as long as I have, yet she still falls for nearly every forwarded urban legend e-mail she gets. She still can't seem to tell fact from fiction on the Internet and she's older than me. I don't know whether I should feel sorry for her in her ignorant bliss or kick her in the butt to wake her up. Some people never learn. But then she also believes in psychics and astrology. Maybe I should have a DNA test done to see if we are really related!
LOL
As far as I'm concerned, psychics, astrologers and their ilk should be deported to Antarctica! I hate pseudoscience, quacks, phony psychics, mystics, astrologers and religious fanatics, especially the ones who wear bombs as a fashion accessory.
I understand your problems with distractions. My interests are so diverse that as soon as I get an idea or an inspiration, I almost forget what I doing and chase after it while it's still ***** in my mind. It's necessary for me to pursue an idea the moment it occurs to me or I could forget to go back to it later. I'm a spaz.
My projects don't generally go unfinished. I eventually get back to them in cycles until they get finished eventually.
My web site is still not ready for public consumption after over a year of work. That's mainly because I'm just learning PHP and keep finding new and better ways to do it and started building a full site before I ******ed PHP sufficiently to achieve my goals. Constantly changing things slows me down.
And now I also have to convert every page to PHP 5. Every page, and there are many of them, that uses POST/GET is broken, so I have to find all those files and then change them.
Sometimes when a project isn't making much progress, I take a break from it and work on some other unfinished project that I put on hold earlier for exactly the same reasons. I must have *00 partly written programs and utility functions at any given moment that may one day finally get finished.
I posted a few of them here already, but I'm not sure if many people have as much use for them as I do.
I need to start my own forum for extreme science and PHP geeks before we go extinct. But that's a bit complicated at the moment.
Whew! That was close. I'm lucky I got one of them before they were all gone!"I think there's a world market for about five computers."

Sorry to take so long to reply. Over the last few days I had to get a new heat sink for my computer. The old one broke loose and I couldn't fix it. Had to replace the whole thing or my system would burn up.
Thanks for the link.
Not sure how long it will work. I was supposed to be moved to a PHP 5 server by my host on the 2*st, but it hasn't happened 2 days after they said they would. As soon as they switch over, most pages will break and need to be fixed when that happens. Still waiting.
