f(x) = e^x

The only function in the world that satisfies ∫f(x)dx = f(x) and d/dx f(x) = f(x). Very dumb.

Question: ∫f(x) = f(x)
Because ∫f(x) = e^x
Therefore, the solution is e^x

When you F up

When one does something really bad they will regret later (unless they have no conscience at all).

I knew a guy who planned a school shooting cuz he got upset over a rumor of him and a girl. Turns out he was joking though he got a felon and it was all over the news. That guy is an example of When you F up.
