Find the antiderivative of
ExpandFoundations:
|
This problem requires three rules of integration. In particular, you need
|
Integration by substitution (u - sub): If is a differentiable functions whose range is in the domain of , then
|

|
We also need our power rule for integration:
|
for .
|
Solution:
ExpandStep 1:
|
Use a u-substitution with This means , or . After substitution we have

|
ExpandStep 2:
|
We can no apply the power rule for integration:

|
ExpandStep 3:
|
Since our original function is a function of , we must substitute back into the result from step 2:
|

|
ExpandStep 4:
|
As will all indefinite integrals, don't forget the constant at the end.
