A study of limits and continuity in multivariable calculus yields many counterintuitive results not demonstrated by single-variable functions. For example, there are scalar functions of two variables with points in their domain which give different limits when approached along different paths. E.g., the function approaches zero whenever the point is approached along lines through the origi…
Calculus III - Functions of Several Variables

May 26, 2020 · First, remember that graphs of functions of two variables, z = f (x,y) z = f ( x, y) are surfaces in three dimensional space. For example, here is the graph of z =2x2 +2y2 −4 z = 2 x 2 + 2 y 2 − 4. This is an elliptic paraboloid and is an example of a quadric surface. We saw several of these in the previous section.

https://www.khanacademy.org/.../a/multivariable-functions
A multivariable function is just a function whose input and/or output is made up of multiple numbers. In contrast, a function with single-number inputs and a single-number outputs is called a single-variable function. Note: Some authors and …

Examples of Multivariable Functions Example 1 A rectangle has a width W and a length L. The area A of the rectangle is given by A = W L. It is clear that if W and L vary, area A depends on two variables: width W and length L. Area A is said to be a function of two variables W and L. Example 2 A rectangular solid has width W, length L and height H. The volume V of the rectangular solid is given by V = W L H.

26.05.2020 · Section 1-5 : Functions of Several Variables. In this section we want to go over some of the basic ideas about functions of more than one variable. First, remember that graphs of functions of two variables, \(z = f\left( {x,y} \right)\) are surfaces in three dimensional space. For example, here is the graph of \(z = 2{x^2} + 2{y^2} - 4\).

In the example above where we studied traces to understand the graph of a paraboloid. For a multivariable function f(x;y), the horizontal traces of z = f(x;y) are often the most useful ones: they capture the families of curves along which the function’s value is constant. We view the
