Math problem

Question

how to solve:

 

a) D[e^2x cos(3x)]

 

b) du(t) / dt, when m(t)= In(t/t₀)²

 

c) m, when m(t)= In(t/t₀)²

 

 

Answer 1

I will give you the first one, the other 2 are not clear enough for a response.  Are b) & c) related?

 

the first answer is: -3e^2xsin 3x + 2e^2xcos 3x
