Sum and Difference Formulas for Cosine and Sine
By YourMathGal
This video explains the sum and difference formulas and how to derive and apply them.
Static Friction and Kinetic Friction Physics Problems With Free Body Diagrams
By The Organic Chemistry Tutor
This physics video tutorial provides a basic introduction into kinetic friction and static friction. It contains plenty of examples and physics problems that asks you to calculate the acceleration using newton's laws of motion. The static frictional force is equal to the applied force up to a maximum value. The kinetic friction force is a constant value that depends on the interaction between the horizontal surface and the object. All frictional forces is dependent on the normal of the object. You should draw a free body diagram for each practice problem if you wish to make it a lot easier.

Integration By Partial Fractions
By The Organic Chemistry Tutor
This calculus video tutorial provides a basic introduction into integrating rational functions using the partial fraction decomposition method. Partial fraction decomposition is the process of breaking a single complex fraction into multiple simpler fractions. The integrals of many rational functions lead to a natural log function with absolute value expressions. This video explains what to do when you have repeated linear factors and quadratic factors. This tutorial contains many examples and practice problems on integration by partial fractions.
