# Thread: Confusing derivative problem :(

1. ## Confusing derivative problem :(

Hi guys,
Im stuck on two simple questions which look the same to me.

1st Q is g(x) = sin(e^5x-1)

2nd Q is y = sin(e^5x)

When I solved it,

the answer for Q1 was 5e^5x cos (e^5x - 1)

Q2 was 5e^5x cos e^5x
However, two questions seem to be all the same except for the -1 part
is it right?
Plz help me guys,

Thank you.

2. It looks good to me.
