Let's evaluate the given integral.
00:02
Here, before we do partial fraction to composition, let's just go ahead and try a u substitution.
00:09
Sometimes making the right choice of you before you do partial fraction to composition will give you a much easier problem.
00:18
Here, let's go ahead and take the differential, 15x plus 5.
00:28
So we have du over 5 is basically, is exactly equal to the numerator of the integer.
00:39
So after our u substitution, we have 1 over u, du, and we also have a pull out this 5 here.
00:54
So in this case, we took a rough looking fraction, made a u substitution, and now look at our partial fraction...
