We never learned how to do a trig substitution... BTW I'm only in Calculus BC. We're just learning the basics of integrating.

Homework Statement integral 1/(x(sqrt(x^2 - 4))) Homework Equations I don't know if there are any "equations" for integrals... The Attempt at a Solution Int(1/(x(Sqrt(4(x^2 /4)-1) Int(1/(2x(Sqrt((x^2 /4)-1) 1/2 int(1/(x(Sqrt((x /2)^2)-1) U-sub u=x/2 du=1/2 dx 2du= dx...
