tangent and cotangent are cofunctions of each other. The tangent of 90-x should be the same as the cotangent of x. This implies that graph of cotangent function is the same as shifting the graph of

Answered: Vhich of the following IS an identity?…
SOLVED: Problem 1. Establish the following identities (a)cot(0=1/tan0) (b)tan20)+1=sec20) (c) cot(0) = cos() sin(0) (d) sin(0) = cos(90 -0) 2tan(0) (f1+sin0)1-sin0)=cos20 (g) sin2(r) = sec2(r) - 1 sec2() (h) tan(-) cot()=-1
