Question

integrate
dx/sqrt(6x-x^2)

Answer 1

You'll probably need a trig substitution, I think...

Answer 2

i was thinking of that but the only sub I know only works for dx/sqrt(a^2-x^2)

Answer 3

Hmm, you might need to complete the square in the denominator first...

Answer 4

then i get dx/sqrt((x-3)^2-9)

Answer 5

which allows for substitution

Answer 6

Yep :)

Answer 7

thanks
