This 9:36 long video introduces the center of mass, the point of location
in which the total mass of the object exists. For example, when forces are applied on the center of mass, the object accelerates with the exact same force applied.

In this video, the instructor talks about trigonometric functions as they relate to right triangles. He defines each function and how to find it using the different sides of right triangles. Then, he does example problems using the definitions of t...he trigonometric functions defined at the beginning. There is a buzzing sound in the background of this video, but the instructor is still able to be heard well.

This two minute videos is about using tangent ratios, which is opposite over adjacent. You use this equation to find side lengths. Right triangles have ratios that are used to represent their base angles. Tangent ratios, along with cosine and sine ra...tios, are ratios of two different sides of a right triangle. Tangent ratios are the ratio of the side opposite to the side adjacent the angle they represent. In order to find the measure of the angle itself, one must understand inverse trigonometric functions. This video shows how this works. It moves rapidly so it is recommended that you stop the video often tor review.
