Trigonometric Ratios

This basic trigonometry video tutorial provides an introduction into trigonometric ratios as it relates to a course in geometry. It explains how to calculate the sin, cos, and tan ratio of a right triangle given the 3 sides. You can use the pythagorean theorem to find the value of the missing side. In addition, it explains how to evaluate trigonometric functions using right triangle trigonometry and special right triangles such as the 30 60 90 triangle or the 45 45 90 triangle. This video contains plenty of examples and practice problems including find missing angles as well as missing sides.
