Answer 8

for:

\(\left( \dfrac{x}{a}\right)^2 + \left( \dfrac{y}{b}\right)^2 = 1\)

let \(u = \dfrac{x}{a}, v = \dfrac{y}{b}\), that's the unit circle, plus be sure to add in the Jacobian

or for line integrals, which ALWAYS have to be expressed in a single parameter, let \(x = a \cos\theta, t = b \sin \theta\), so \(\theta\) is THAT parameter

but quite hard to help w/o a concrete example
