The derivative of a function at a given point represents the rate of change of the function at that point. One of the applications of derivatives is to determine velocity and acceleration of an object in motion. Applications of integrals include calculating areas of plane regions or surfaces, as well as calculating volumes of solids. Both derivatives and integrals are defined using the concept of limit. Calculus of Variations Submit sites that are beyond basic calculus that focuses on finding the minima and maxima of functions.
Calculus of variations is the study of finding minima and maxima of functions.
Multivariable Calculus Submit sites to this category that are about calculus of equations with three or more variables. Calculus using more than the usual two variables x and y in a function. The most common multivariable function would have three variables x,y and z, with z being the dependent variable.
