Question

what does a real function of two independent variable represent?​

Answer 1

Step-by-step explanation:

A function of two independent variables, z=f(x,y)

Defines a surface in three-dimensional space.

For a function of two or more variables, there are as many independent first derivatives as there are independent variables.

For example, we can differentiate the function z=f(x,y) with respect to x keeping y constant.
