## 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
