This computer science video is one of a series on linear algebra for computer scientists. The study of linear algebra requires an understanding of trigonometry, indeed, the two are inextricably linked. In this video you will learn about the three trigonometric functions which relate an acute angle of a right angle triangle to the ratio of the lengths of two sides, namely, the Sine, Cosine and Tangent functions. You will learn how these functions can be derived and will see the origin of some well-known trigonometric ratios.
