Ht=integral of:(((1-omega)*a^-1+(omega*a^-2))^-1/2)da

Hi birdhen! Welcome to PF! :smile:

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

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

in other words, put the bracket into the form something2 ± a constant. :smile:
