I am having problems trying to solve the following problem and wondered if anyone could point me in the right direction..

Ht=∫(da/√((1- ω)*a^{-1}+(ω*a^{-2}))

cheers

Hi birdhen! Welcome to PF!

(have an integral: ∫ and a square-root: √ and an omega: ω )

Hint: multiply top and bottom by a (to get rid of the nasty inverses ), and then complete the square …

in other words, put the bracket into the form something
