The cosine of the angle = the length of the adjacent side The tangent of the angle = the length of the opposite side the length of the adjacent side. So in shorthand notation: sin = o/h cos = a/h tan = o/a Often remembered by: soh cah toa how to get puk code for apple iphone sine, cosine, tangent, cotangent, secant, cosecant. Exact values of trigonometric functions for some most used acute angles. Trigonometric functions of an acute angle are ratios of different pairs of sides of a right-angled triangle ( Fig.2 ) . 1) Sine: sin A = a / c ( a ratio of an opposite leg o a hypotenuse ) . 2) Cosine: cos A = b / c ( a ratio of an adjacent leg to a hypotenuse ) . 3

## How To Find Sine Cosine And Tangent

Sine, cosine, and tangent all assume you have a right triangle (where one angle is 90 degrees). Each function operates on one number, which represents another angle (call it x) in the triangle.
