Question

Find the derivative of h(t)=t tan t + sin t
I solved and got 0 but is says its wrong any help would be appreciated.

Answer 1

h'(t) = t sec^ t + tan t + cos t

Answer 2

Hmm I must be typing this in wrong ;/

Answer 3

Can anyone else double check cwrw2s answer?

Answer 4

By using the product rule I got

h'(t)=tsec^2(t)+tan(t)+cos(t)

Answer 5

woot that was it! thanks!

Answer 6

Do you understand how we got it?
