Example of simplifying a Boolean expression by using a 3-variable Karnaugh map.

Worked example for solving limits where x is approaching infinity. Includes graph of the function, explanation of the steps involved and why these steps are taken.

We derive a formula to simplify the process of taking the curl of the curl of a vector field. The algebra is rather complicated!

After completing this module students should be able to define the force vector in a plane, solve the vector operations, determine the rectangular components of a force, calculate the addition of forces by summing X and Y ...

This screencast illustrates the method of separation of variables for a medium-level first order differential equation: dv/dpsi=v(tan(psi)-mu sec(psi)).

This video explains the appropriate notation to denote the composition of functions.

Example of solving a second-order linear ordinary differential equation with constant coefficients in the case where the auxiliary equation has complex conjugate roots and the right hand side of the equation is an exponential ...

This screencast first gives the general form of Cramer's Rule for solving three equations in three unknowns and then covers a specific example to demonstrate the rule.

Explains what a quadratic inequality is with use of a diagram to show the difference between solving inequalities and solving equations.

A demonstration of how to set up a truth table for a Boolean expression, in the context of a particular example.
