So I'm not really sure how to go about this problem. I've attempted letting x = a few things. 4sinx, and 4tanx. Maybe trig substitution is not even the way to go. Could someone push me in the right direction?

1. The problem statement, all variables and given/known data

2. Relevant equations

3. The attempt at a solution
