In this lecture you will learn how to calculate the Area Between Curves using Calculus. Our teacher first begins with a Graphical Description before rounding out the lecture with five video examples.

Area Between Curves
I recommend always
starting with a sketch and drawing in a sample rectangle.
If an interval is
not given, you may need to set the two functions equal in order to
determine the interval involved.
If two curves
cross, then you will need to break up the integral into more than
one integral.
Sometimes,
geometrical considerations can help you to check your results or
even provide a non-calculus way to finish a problem.
