13 - Evaluation Limits

When you have a definite integral, you know that it's evaluated between two bounds a and b.

More often than not, you won't use the same expression F(b) - F(a) a hundred times, so this is where we introduce the evaluation limits. It's a little vertical bar you add in at the end of the equation followed by the upper and lower evaluation limit. This means that you'll take the equation for the top value and subtract the same equation for the bottom value from it.
