Tangent is the reciprocal of cotangent
WebScore: 4.6/5 (53 votes) . Trigonometric functions are undefined when they represent fractions with denominators equal to zero. Cotangent is the reciprocal of tangent, so the cotangent of any angle x for which tan x = 0 must be undefined, since it would have a denominator equal to 0. Webcotx = 1/tanx = cosx/sinx secx = 1/cosx cscx. = 1/sinx As you can see, if secx= 1/cosx, then sec²x= (1/cosx)² = 1/cos²x, similarly, -csc²x = - 1/sin²x They are equivalent, either is fine. It's personal preference but depends on how you are asked to simplify.

WebReview all six trigonometric ratios: sine, cosine, tangent, cotangent, secant, & cosecant. ... Reciprocal functions were used in tables before computer power went up and there are some instances where calculating an inverse of a function is easier than the function. WebThe Cotangent Function The cotangent function is the reciprocal of the tangent function. Thus, The graph of will have asymptotes at the zeros of the sine function (Figure 4.48) and zeros at the zeros of the cosine function (Figure 4.49). y = cot x cot x = cos x sin x.

WebCsc sec cot are which thre mathematical functionalities cosecant, secant, and cotangent respectively. Csc sec cot are based on the others thrice trigonometric functions sin, cos, and umber, respectively. WebThe other four trigonometric functions (tan, cot, sec, csc) can be defined as quotients and reciprocals of sin and cos, except where zero occurs in the denominator. It can be proved, for real arguments, that these definitions coincide with elementary geometric definitions if the argument is regarded as an angle given in radians. [6]
