What's your favorite math/science equation?

<p>Distance formula</p>

<p>d=sqrt[(x2-x1)^2+(y2-y1)^2]</p>

<p>ftw</p>

<p>Also volume of a sphere
V=(4/3)<em>pi</em>r^3</p>

<p>I’m pretty fond of x=x and 1+1=2, personally.</p>

<p>Also, Euler’s identity. It’s a predictable choice for favorite equation but it’s for good reason: e^(i*pi) + 1 = 0</p>

<p>The Hardy-Weinberg equation, of course.</p>

<p>(p^2) + (2pq) + (q^2) = 1</p>

<p>I hate math.</p>

<p>

Okay, fine. Would x + x =2x satisfy you? ;(</p>

<p>s’(e^xy)= e^xy</p>

<p>There are three that I really love:</p>

<p>E(x) = summation(xipi)
F = dp/dt
(statistic - parameter)/standard deviation of statistic</p>

<p>y"+y’+y=0</p>

<p>i love me some homogeneous equationz!</p>

<p>

</p>

<p>I suppose if you want to be that boring your original equation was okay to begin with…since you actually did do your math right (wow!)</p>

<p>btw: I don’t get how meadow36 translates in to I’mam34dowololzzz?</p>

<p>

It really shows. Thanks for making my day with this horrible attempt at epic lulz.</p>

<p>I’ve loved the Pythagorean Theorm since sixth grade. lol</p>

<p>It’s my favorite. </p>

<p>Sad, but true.</p>

<p>Wow, why did I make this thread? I must have been high.</p>

<p>integral of e to the x = f(u)n</p>

<p>^Hahahaha I got that bumper sticker on FB.</p>

<p>Wow, I am now officially embarrassed to ever visit CC.</p>

<p>But how about…
2ada/dt+2bdb/dt=2cdc/dt
:] only spoken aloud, of course.</p>

<p>the equation of trajectory</p>

<p>A^2 - b^2 = (a+b)(a-b)</p>

<p>The Reciprocal rule has been very helpful:</p>

<p>(1/g(x))=-g’(x)/(g(x))^2</p>

<p>I’m sorry, but all of your math equations suck.</p>

<p>\int<em>M d\omega = \int</em>{\partial M} \omega, or, for the non-LaTeX people:</p>

<p><a href=“http://upload.wikimedia.org/math/9/8/d/98da50d6b2b3b0abc3de5994d98c5562.png[/url]”>http://upload.wikimedia.org/math/9/8/d/98da50d6b2b3b0abc3de5994d98c5562.png&lt;/a&gt;&lt;/p&gt;

<p>Points to anyone who knows the name of the theorem (and can state it precisely, while explaining what all the symbols, including d, M, \omega, and \partial \omega, mean).</p>

<p>f = ma</p>

<p>really easy.</p>

<p>The equation to determine escape velocity. Lol.</p>
