Steps for U­Substitution and Integration

1. Choose a substitution (Usually              ) Note: It generally works best to let          be the inner portion of composite function.

2. Compute 

3. Re­write the integral in terms of the variables      and        .  (If not possible try to re­write    in terms of       instead:(  (If still no cannot be done by substitution)

4. Determine resulting integral in terms of    .

5. Re­write integral in terms of     to determine the anti­derivtive of   .

6. Check by differentiating.
