This linear algebra video covers a tutorial on solutions to linear systems with three unknowns. It gives a geometric interpretation of the solutions which are grouped into three categories, no solution, one solution and infinitely many solutions.

This computer science video covers a tutorial on using recursion to traverse arrays. Example code is provided to show the difference between the recursive and iterative implementations.

This chemistry video covers a tutorial on the Maxwell-Boltzmann distribution of velocities for an ideal gas or a mixture of ideal gases. The distribution of velocities for two cases are given, the same ideal gas at different temperatures and a mixture of ideal gases at the same temperature.

This calculus video covers a tutorial on how the second derivative can be used to determine if a critical point is a local minimum or a local maximum.

This physics video covers a tutorial on the equilibrium of an extended rigid body. For a rigid body to be in equilibrium, both the net force and net torque acting on the body must be zero. A worked example is covered to enhance your understanding.
