# Integration help watch

1. When asked to find the integral of a function does this really mean the area under the curve or does it simply mean just sub limits into integral regardless of whether there is area below the x axis.

this is when area under curve is not specifically asked for.

Integration can be used for much more than finding areas. For example, you might integrate to find volumes or masses.

Do you mean if a question gives you an integral with limits and just says "evaluate it"? In this case, yes, you just integrate the function and substitute the exact limits at the end.

If you are asked to find the "area" between a curve and the axis, and one part of the curve lies above and another below, then you have to adjust for that.
