   1. The problem statement, all variables and given/known data
   
   
   2. Relevant equations
   
   3. The attempt at a solution
   I'm not asking for someone to do the question for me but I was just wondering what I'm supposed to sub in. Do I put in as if it was (x^2-9)^(1/2) or do I have to do something differently if there is a constant in front of the x^2? Thanks for any help.

   You are correct, secant is the correct trig function to use in this case.
   However the coefficient is incomplete, you need to divide out the 4 as well.

   So is it x=(3/2)sec(theta) ?
