If we differentiate the denominator in the integrand
![]() |
we obtain almost the same expression as in the numerator; there is a constant 2 which is different. We therefore rewrite the numerator as
![]() ![]() ![]() ![]() |
so the integral can be written as
![]() ![]() ![]() ![]() |
and we see that the substitution
![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() |
In the last step, we take away the absolute sign around the argument in
