Question

find the derivative of e^(t)cos(t)/t

Answer 1

I can tell you that you will be using product and quotient rule for this

Answer 2

quotient rule yes. but product rule?

Answer 3

if that numerator has two terms in it. confirm that you wrote the problem correct

Answer 4

t * e^(t)-sin(t)-e^(t)cost(t) (1)/t^(2)

Answer 5

that looks about right.

Answer 6

ok but then what? this is where im lost

Answer 7

that is the final answer. when you can not combine terms - then stop
