Question

How can I find the critical points of this

Answer 1

\[e ^{-x}sinx\]

Answer 2

I know you get the derivative which in this case is \[e ^{-x}cosx-sinx\]

Answer 3

where to go from there?

Answer 4

Whereever it equals 0

Answer 5

ok so i guess this thing just has a crap load of critical points

Answer 6

Do you have a interval you are looking at?

Answer 7

no, it really just asks for all the significant features of the equation. answers for odd problems give critical points so i need it for this
