Integral calculus is the study of the area under curves. It is used to find the area of regions bounded by curves, the volume of solids of revolution, the work done by a force, and the amount of fluid flowing through a pipe. Integral calculus is a powerful tool that is used in many fields of science and engineering.
What is the area under the curve of f(x)=x^2 from x=0 to x=4?
What is the integral of x^2 from x=0 to x=1?
