There is no direct way to visualize a function of 3 variables, as it is an object (surface) which lives in 4 dimensions. One must play with slices of the function to see what's going on. By a slice, I …

Two variables are easy to visualize using plots such as 2D scatter plots, bivariate histograms, and box plots. You can also visualize trivariate data with 3D scatter plots, or 2D scatter plots with a …

One way to try to get a handle on higher dimensional data is to try to fix values of some variables and visualize the values of others in 2D. This can be done with interactive tools;

Functions of \(3\) variables. For a function \(f:\R^3\to \R\), we can still define the graph \[ \{ (x, y, z, w) \in \R^4 : w = f(x,y,z) \} \] For most humans, however, it is very hard to form a mental picture …

Visualizing functions of several variables. There are many ways to interpret a function of several variables. Two very common ways to do this are to consider the surface obtained by graphing …

A tool for visualizing functions that is sometimes as powerful as graphs is using mapping diagrams. The simple idea is that each real variable is represented on an independent parallel …

functions of three variables through their graphs. We can visualize functions of three variables through level surfaces. Level surfaces are analogous to level curves for a function of two …

Today we will begin studying functions of several variables. We will focus on elementary concepts such as domains and graphs. The graph of a two-variable function is a surface in R3. The …

Subsection 11.2.5 Visualizing Functions of Three or More Variables. Unfortunately, we are not able to visualize functions of three or more variables very easily, as we would need to visualize …

The graph of a function of three variables would require a four dimensional plot, which is beyond MATLAB's capabilities, but we can draw a picture of a single level surface of the function. This …
