## anonymous 3 years ago Find the derivative: $$\ \frac{2}{(1+e^{-x})}$$

1. anonymous

what's the derivative of e^x

2. anonymous

e^x

3. anonymous

quotient rule if u want.

4. anonymous

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

5. anonymous

Or is that okay?

6. anonymous

try it out, let me know what u get.

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

8. anonymous

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