How do you evaluate the integral #int ln(3x+4)#?
Integration by Parts states:
Let's use u-substitution. Let
Taking out the constant, the problem becomes,
Now, we use integration by parts, which is:
Now, we plug that back into the original integral.
Notice how I don't put in the constant yet, as we always put the constant after the final calculation, and not during the calculation, as
Now, we can add the constant.
