If you're a beginner, it helps to write every term (if possible) in the form
Then you can remember that the antiderivative is
So in this case, you'd have .
Can you find this antiderivative using the formula?
If you're finding a definite integral, once you have the antiderivative, substitute the upper limit and see what you have ( , substitute the lower limit ( ) and see what you have, then do .
