Question

How would you find the derivative of e^xcosx using the chain rule?

Answer 1

I love it when I look in the questions section and find one un-answered about calculus haha
So do we have:
\[\eqalign{
&A.\phantom{..}f(x)=e^xcos(x)\\
&B. \phantom{..}f(x)=e^{xcos(x)} \\
}\]
Which one?

Answer 2

guess you'll never know

Answer 3

Haha well I'm just making sure.

Answer 4

I assume that it would be B since he is referring to the chain rule. But it never hurts to make sure.
