what's the derivative of e^x

Answer 2

e^x

Answer 3

quotient rule
if u want.

Answer 4

What's confusing me is with that wouldn't that result in multiplication by 0?

Answer 5

Or is that okay?

Answer 6

try it out, let me know what u get.

Answer 7

or you could use chain rule, given the formula
d/dx(1/x) = -1/x^2

Answer 8

d/dx(2/(1+e^(-x))) = (2 e^x)/(e^x+1)^2

Answer 9

how did you do that? the drawing

Answer 10

screenshot.whatever.
