The identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot2θ = csc2θ. 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side. = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with the common denominator. = sin2θ + cos2θ sin2θ = 1 sin2θ = csc2θ.Below are some of the most important definitions, identities and formulas in trigonometry. Trigonometric Functions of Acute Angles sin X = opp / hyp = a / c , csc X = hyp / opp = c / a tan X = opp / adj = a / b , cot X = adj / opp = b / a cos X = adj / hyp = b / c , sec X = hyp / adj = c / b , Trigonometric Functions of Arbitrary Angles

We know that the function has a limit as x approaches 0 because the function gives an indeterminate form when x=0 is plugged in. Therefore, because the limit from one side is .
Beware - the notation cos-1 have two very different meanings: cos-1 (x) = 1/cos (x), i.e., the multiplicative inverse of cos (x); or. cos-1 (x) = arccos (x), i.e., the inverse function of the cosine. In other words, we have the problem of determining the angle whose cosine equals x. We assume that you have in mind the inverse cosine.
