Mathematical Command Functions

The video tutorial covers the use of various mathematical commands such as show, point, solve, and nsolve. It explains how to set plots to variables, graph functions and points in 3D, and solve equations both analytically and numerically. The tutorial also demonstrates how to manipulate plots and use commands to find solutions within specific domains.
