Sin Cos Tan Formulas. Sin, cos, and tan functions in trigonometry are defined in terms of two of the three sides (opposite, adjacent, and hypotenuse) of a right-angled triangle. Here are the formulas of sin, cos, and tan. sin θ = Opposite/Hypotenuse. cos θ = Adjacent/Hypotenuse.

Sin cos tan values are the primary functions in trigonometry. Learn the values for all the angles, along with formulas and table. Also, learn to find the values for these trigonometric ratios.
Sine, Cosine and Tangent. Sine, Cosine and Tangent (often shortened to sin, cos and tan) are each a ratio of sides of a right angled triangle: For a given angle θ each ratio stays the same no matter how big or small the triangle is. To calculate them: Divide the length of one side by another side
Trigonometric table comprises trigonometric ratios – sine, cosine, tangent, cosecant, secant, cotangent. These ratios, in short, are written as sin, cos, tan, cosec, sec, and cot. The values of trigonometric ratios of standard angles in a trig table are essential in solving trigonometry problems.
When 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) to get:
