Trig function cosine
WebLaw of Cosines in Trigonometry. The law of cosine or cosine rule in trigonometry is a relation between the side and the angles of a triangle. Suppose a triangle with sides a, b, … WebFor example the inverse function of COS is ARCCOS. While COS tells you the cosine of an angle, ARCCOS tells you what angle has a given cosine. See Inverse trigonometric functions. On calculators and spreadsheets, the inverse functions are sometimes written acos(x) or cos-1 (x). Trigonometry functions of large and/or negative angles

WebNotice in particular that sine and tangent are odd functions, being symmetric about the origin, while cosine is an even function, being symmetric about the y-axis. The fact that you can take the argument's "minus" sign outside (for sine and tangent) or eliminate it entirely (for cosine) can be helpful when working with complicated expressions.
