What is calculus?
Rates of change - Limits - The derivative - Applications of the derivative - Applications of intergration.
Calculus answers two basic questions: how do you find instantaneous rates of change, and how do you find the area under a curve?
The derivative is an equation that gives the slope of the line tangent to a function. IKt is the basic of differential calculus which solves the instantaneous rate problem.
An integral undoes a derivative, giving back the original function. Integral calculus goes backwards from differential calculus and solves for area under a curve.
