Homework Statement
√(9-x²) / (x²)
Homework Equations
Just trig substitution
The Attempt at a Solution
Ok, for trig sub I did
u=asinΘ
x=3sinΘ
9-x²=9-9sin²=9(1-sin²Θ)
so putting it into the equation
√9cos²Θ=3cosΘ/x^2
where do I go from here, I tried getting help at Math forum, but they were complete tools. Plus I have had a good experience with this site in the past
