Under Graduate Calculus I & II

Calculus is a branch of mathematics that involves the study of rates of change. Before calculus was invented, all math was static: It could only help calculate stationary objects. But the universe is in constant motion and changing its form. No objects—from the heavenly bodies in space to subatomic particles or cells in the body—are always at rest. Indeed, just about everything in the universe is constantly moving. Calculus helped to determine how particles, stars, and matter move and change in real-time.
