Help me "get" this really bad joke...

Colleges & Universities California Institute of Technology

<p>In the magical joke world where functions of a real variable are anthropomorphized, 1 and e^x are walking down the street.</p>

<p>Suddenly 1 stops, points across the street and says, “Oh no; there’s The Derivative. The Derivative will annihilate me.”</p>

<p>e^x says, “Have no fear. I can meet The Derivative and return unscathed.” So e^x walks confidently across the street, goes up to The Derivative and says, “Hello, I’m e^x.”</p>

<p>The Derivative responds, “Hi. I’m d/dy.”</p>

<p>haha, that’s wonderful. :D</p>

<p>I assume you realize that a derivative takes ‘1’ to zero, but the derivative of e^x is just e^x (the derivative of e^x is written as d/dx (e^x)). The derivative with respect to a different variable (in this case, y), however, takes e^x as a constant, so it’s derivative is zero.</p>

<p>Hopefully that makes some sense.</p>

<p>e^x is a function which, derivated by x gives e^x again.
or… d/dx(e^x)=e^x. (That’s why the function wasn’t first afraid of the Derivative)
But, supposing that x does NOT depend on y, we can conclude that d/dy(e^x)=0</p>

<p>Tough day for e^x :D</p>

<p>It’s not that bad a joke after all.</p>

<p>hahahaha, I get it now. Wow, that’s pretty good.</p>

<p>If you guys wanna see a kinda lame math joke, I did some graphic design jokes on two of my math teachers. One features a calculus love song that I wrote and the other has the teacher’s favorite math joke–bonus points to whoever finds and explains it.</p>

<p>Oh, and if you have trouble reading the text in arup is on fire at the bottom it says “If thine eyes are so imbued with sagacious perception thou wilt be so the more enlightened and thou wilt know that…”</p>

<p>ahahahhaha awesome!</p>

<p>hrm, is it just sex = fun? or am I not seeing something
it’s kinda wrong though (the equation its self) but that’s ok.</p>

<p>here’s a funny video of a physics/math love song by the Klein Four Group (some of you might have seen it):

<p>^^ That’s amazing!</p>

<p>no, it’s just sex = fun :stuck_out_tongue: I did say it was kinda lame. Bonus points to you. Arup (the teacher) told me that joke when I showed him my Caltech box (part of the app as you all know)… my box was on “The equation for happiness”. He says that’s his equation for happiness :P</p>

<p>Isn’t “Finite simple group of order two” really redundant? It has a nice ring to it though.</p>

13

<p>lol, that’s a good one.</p>

14

<p>hehe… I love math jokes</p>

<p>integral[d(cabin)/cabin] = houseboat</p>

<p>One of my favorite “inside” jokes involving math is the symmetric group acting on m elements (Sm). It’s especially fitting considering that the “S” is capital and the “m” is lowercase.</p>
