Question

Find the derivative of g(x) = e^theta/cos(theta)

Answer 1

This is what I did

Answer 2

\[e^\theta/\cos(\theta)\]
\[(\cos(\theta))(e^\theta)-(e^\theta)(-\sin(\theta))/(\cos(\theta))^2\]

Answer 3

then

Answer 4

\[e^\theta \cos(\theta)+e^\theta \sin(\theta)/(\cos(\theta))^2\]

Answer 5

Is that right?
