1. The problem statement, all variables and given/known data
limit as x goes to infinity of (1/x^2)  (cscx)^2 2. Relevant equations 3. The attempt at a solution I made it so the denominator is x^2, but then it would 1inf/inf which isn't indeterminate. i need help setting it up so it would be in indeterminate form. thanks.

You probably mean lim x>0, right? Just make a common denominator and combine those two terms into a single fraction. It's probably easier to write 1/sin(x)^2 instead of csc(x)^2, but it will still take several derivatives before you get a nonindeterminant answer from l'Hopital.

nope, the question states lim x> inf
