Question: `q001. Find the first and second derivatives of the following functions:

3 sin(4 t + 2)

2 cos^2(3 t - 1)

A sin(omega * t + phi)

3 e^(t^2 - 1)

YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY

Your solution:

First derivatives: 3 sin(4 t + 2),A sin(omega * t + phi),2 cos^2(3 t - 1)

Second derivatives: 3 e^(t^2 - 1)

@&

You don't appear to have done any derivatives.

For example the first derivative of 5 cos(3 t - 4) would be -15 sin(3 t - 4), and the second derivative would be 45 cos(3 t - 4).
