How do you find the integral of #(1 + e^2x) ^(1/2)#?
Integrate by method of substitution.
(1) Let u =
(2) Take the square of u, hence,
(3) Take the derivative of both sides, hence,
(4) Substitute 'u' and 'du' to the original differential eqn.
(6) Replace 'u' in terms of 'x' by using the defined value of 'u'
