Answer Each of these functions are derived in some way from sine and cosine The tangent of x is defined to be its sine divided by its cosine The secant of x is 1 divided by the cosine of x sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x csc x = 1 sin xIn various applications of trigonometry, it is useful to rewrite the trigonometric functions (such as sine and cosine) in terms of rational functions of a new variable These identities are known collectively as the tangent halfangle formulae because of the definition of These identities can be useful in calculus for converting rational functions in sine and cosine to functions of t in order The sine of the angle = the length of the opposite side the length of the hypotenuse The cosine of the angle = the length of the adjacent side the length of the hypotenuse The tangent of the angle = the length of the opposite side the length of the adjacent side Moreover, what is sin in terms of COS?
