Intergrate these:
(x^2) dx
(2+3x)^1/2
and
(x^2-25)^1/2 dx
x
We have to intergrate them using parts and it's so frustrating because i just don't know how to do it! please help, thank you!
.
Remember the rule for integration by parts:
Letting and , so and
Now we will leave the first part of this equation alone just for now and deal with the second part which requires another integration by parts.
Let and . So and
Now, returning to the equation we left off from, the solution to this problem is:
If needed it can be simplified:
Now you try do the other one...
