In pre-calculus, you can rest easy knowing that a geometric shape is always basically the same, so you can find its area with a formula using certain measurements and a standard formula. No more nice, pretty formulas to find area here; instead, you use a process called integration which can also be termed nice and pretty. Calculus: You study the volume of interesting shapes called solids of revolution.

The geometric solids you find volume for prisms, cylinders, and pyramids, for example have formulas that are always the same, based on the basic shapes of the solids and their dimensions.

The way to find the volume of a solid of revolution, though, is to cut the shape into infinitely small slices and find the volume of each slice. Calculus: You study objects moving with acceleration.

### An Overview of Precalculus Topics

Using algebra, you can find the average rate of change of an object over a certain time interval. Using calculus, you can find the instantaneous rate of change for an object at an exact moment in time. Calculus: You study changes to functions in terms of x, with those changes in terms of t. Graphs of functions referred to as f x , can be created by plotting points.
