WebTrigonometry Ratios-Sine, Cosine, Tangent. The trigonometric ratios of a triangle are also called the trigonometric functions. Sine, cosine, and tangent are 3 important trigonometric functions and are abbreviated as sin, cos and tan. Let us see how are these ratios or functions, evaluated in case of a right-angled triangle. WebWe wish to prove the following trig identity: 1 − tan (θ) cos (θ) + 1 − cot (θ) sin (θ) = sin (θ) + cos (θ) a. First, begin by rewriting each of the trig functions on the left hand side of the …
