Big Picture: Derivatives

Calculus finds the relationship between the distance traveled and the speed — easy for constant speed, not so easy for changing speed. Professor Strang is finding the “rate of change” and the “slope of a curve” and the “derivative of a function.”

Professor Strang’s Calculus textbook (1st edition, 1991) is freely available here.
