sec = 1/cos

so

cos*sec = 1

geerky42 · Answer

Ok, like @dumbcow said, $\cos\theta\sec\theta=1$, so you now have $\dfrac{1}{\tan\theta}$, right?

Just remember that $\tan\theta = \dfrac{\sin\theta}{\cos\theta}$.

ok i see. so what would i put for f(u) and g(u)? when i plugged in 1 for f(u) it was wrong and when i plugged in sinu/cosu for g(u) it also was wrong. Did i do this wrong?

geerky42 · Answer

It's because you still need to simplify further.

You have $\dfrac{1}{\tan\theta} = \dfrac{1}{\dfrac{\sin\theta}{\cos\theta}}$

Know what to do next?

yeah you get costheta/ sintheta right?
