Ht=∫(da/√((1- ω)*a-1+(ω*a-2))

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 something2 ± a constant.

thank you!
