ok, i am almost positive this is going to end up involving an inverse trig function, since thats the section its in

ive been going at it for a while and cant get anything to work

(integral) 1/((x-a)(b-x)) dx b=/=a

it says Hint: x-a= (b-a)(sin^2 u)

i plugged that in, and got little help.. any help is greatly appreciated as always
