# e^-x watch

1. What do you get when you integrate and differentiate e^-x.

I understand that with e^x you get the same result when its integrated or differentiated but is this the case with e^-x??

when u integate you get -e^(-x) + K(a constant)
differentiate you get -e^(-x)

INT e^ax = (1/a)e^ax + C
d/dx (e^ax) = ae^ax.

You can easily prove the results to yourself using the chain rule or integration via substitution.
