2x
=dx
Evaluate f
Solution
Steps
Rewrite rational expression to exponential expression to
make the function integrable.
Find two functions within the integrand that forms a
function-derivative pair to do so, we find an "inner
function" with its derivative being multiplied outside of it.
3.)
Next that we need is to have a simplified integrant,
which is now all in terms of u, no x variables at all.
1.)
2.)
Let u = x2 - 1, du = 2xdx
S(x? – 1) x 2 xdx
du
4.)
Integrating by integral formula fu"du =
un+1
%3D
+ C.Then,
n+1
simplify the numerical coefficient.
The original equation never had a "u", the original question has x's.
5.)
To find the final answer, substitute u = x2- 1 .
