WebWhen we divide Sine by Cosine we get: sin (θ) cos (θ) = Opposite/Hypotenuse Adjacent/Hypotenuse = Opposite Adjacent = tan (θ) So we can say: tan (θ) = sin (θ) cos (θ) That is our first Trigonometric Identity. Cosecant, Secant and Cotangent We can also divide "the other way around" (such as Adjacent/Opposite instead of Opposite/Adjacent ): 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.
