With our sine cosine tangent calculator, you will learn everything you need about the most important trigonometric functions: discover how to identify them, their relationship to right triangles, and how to calculate them in the blink of an eye!
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
Once you know the value of sine and cosine, you can use the following trigonometric identities to obtain the values of the other four functions: Tangent is the sine-to-cosine ratio. tan(α) = sin(α)/cos(α) Cosecant is the reciprocal of the sine. csc(α) = 1/sin(α) Secant is the reciprocal of the cosine. sec(α) = 1/cos(α)
1. Here, we show you a step-by-step solved example of trigonometric identities. This solution was automatically generated by our smart calculator: $\sec\left (x\right)^2+\csc\left (x\right)^2=\frac {1} {\sin\left (x\right)^2\cdot\cos\left (x\right)^2}$. 2. Starting from the left-hand side (LHS) of the identity.
