Review the law of sines and the law of cosines, and use them to solve problems with any triangle. Law of sines. a sin ( α) = b sin ( β) = c sin ( γ) Law of cosines. c 2 = a 2 + b 2 − 2 a b cos ( γ) Want to learn more about the law of sines? Check out this video. This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. The Sine, Cosine and Tangent functions express the ratios of sides of a right triangle. Sine, cosine and tangent are the primary trigonometry functions whereas cotangent, secant and cosecant are the other three functions. The trigonometric identities are based on all the six trig functions. Check Trigonometry Formulas to get formulas related to trigonometry. Table of Contents: Definition. List of Trig Functions.

From the sin graph we can see that sinø = 0 when ø = 0 degrees, 180 degrees and 360 degrees. .
