Basis of trigonometry: if two right triangles have equal acute angles, they are similar, so their corresponding side lengths are proportional In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) [1] are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. The functions tangent and cotangent both have a period of pi. We will also cover evaluation of trig functions as well as the unit circle (one of the most important ideas from a trig class!) and how it can be used to evaluate trig functions. In this video we will look.
