## Study23 Group Title Find the derivative: $$\ \frac{2}{(1+e^{-x})}$$ one year ago one year ago

1. infoshark

what's the derivative of e^x

2. Study23

e^x

3. infoshark

quotient rule if u want.

4. Study23

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

5. Study23

Or is that okay?

6. infoshark

try it out, let me know what u get.

7. hartnn

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

8. ninjin

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