A function of numerous real variables, also known as a real multivariate function, is a function having more than one parameter, all of which are real variables in mathematical analysis. This concept broadens the concept of a function of a real variable to include many variables.

Real values are used for the "input" variables, whereas the "output," also known as the "value of the function," might be real or complex. However, by studying the real and imaginary components of the complex function, the study of complex-valued functions may be simply reduced to the study of real-valued functions; hence, unless otherwise mentioned, only real-valued functions will be addressed in this article.

In this “Functions of Several Variable - Mathematics I” you will learn about the following topics:

- Concepts of Functions of Several Variable
- Partial derivative
- Homogeneous function
- Euler’s theorem
- Differentiation
- Second & Higher order
differentials
- Implicit functions.
