Sin Cos Tan Values In trigonometry, sin cos and tan values are the primary functions we consider while solving trigonometric problems. These trigonometry values are used to measure the angles and sides of a right-angle triangle. Apart from sine, cosine and tangent values, the other three major values are cotangent, secant and cosecant. Simplify: tan^2(x) cos^2(x)+ cot^2(x) sin^2(x) trigonometric-simplification-calculator.

Plot of Sine
The Sine Function has this beautiful up-down curve (which repeats every 2π radians, or 360°).
It starts at 0, heads up to 1 by π/2 radians (90°) and then heads down to −1.
Plot of Cosine
Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again.
Plot of Sine and Cosine
In fact Sine and Cosine are like good friends: they follow each other, exactly π/2 radians (90°) apart.
Plot of the Tangent Function
The Tangent function has a completely different shape ... it goes between negative and positive Infinity, crossing through 0, and at every π radians (180°), as shown on this plot.
At π/2 radians (90°), and at −π/2 (−90°), 3π/2 (270°), etc, the function is officially undefined, because it could be positive Infinity or negative Infinity.
