Differentiate uu to find dudu. If your dudu does not match what’s left inside the integrand perfectly, you must rearrange your dudu so that it does match perfectly.

Substitute uu and dudu into the integrand, and integrate using the key integration formulas that are already familiar to you.

Substitute the original value for uu back into the equation after integrating. Remember to add the constant of
