Which equation are you?

[j4]

You are... Euler's equation! ep + 1 = 0 Known to many but understood by few, you encompass a wide variety of different ideas in one small, neat package. You have little practical value but your beauty is greatly appreciated by the few who are qualified to unravel your mysteries. Choose your own answer!

e_p?

The fact that e to the power of pi times i is equal to -1 is actually rather useful in a lot of electrical engineering.

So, what did you do yesterday lunchtime?

Would saying I only agree with the second half be shooting fish in a barrel, do you think ?

H(phi) = E(phi), given that I'm allegedly a condensed-matter physicist.

(Also, e(i*pi) = -1 is staggeringly useful and important to anyone who's ever wrangled with differential equations, which is quite a lot of people.)
