# What are the names of the trigonometric functions?

## What are the names of the trigonometric functions?

The six trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant and Cotangent. What is the use of trigonometric functions? In geometry, trigonometric functions are used to find the unknown angle or side of a right-angled triangle. What are the three basic trigonometric functions?

Which is the most important identity of trig functions?

This is probably the most important trig identity. Identities expressing trig functions in terms of their complements. There’s not much to these. Each of the six trig functions is equal to its co-function evaluated at the complementary angle. Periodicity of trig functions.

How are COs and SEC functions related to trig functions?

Below are the identities related to trig functions. The cos and sec functions are even functions; the rest other functions are odd functions. The trig functions are the periodic functions. The smallest periodic cycle is 2π but for tangent and the cotangent it is π. Where n is any integer.

### How to calculate the trigonometric ratio of sin?

The trigonometric ratio table for six functions like Sin, Cos, Tan, Cosec, Sec, Cot, are: By now we have known the formulas and values for different angles for all the trigonometric functions. Let us see here the graphs of all the six trigonometric functions to understand the alteration with respect to a time interval.

How are inverse trigonometric functions used in computer programming?

Notation. Thus, in the unit circle, “the arc whose cosine is x” is the same as “the angle whose cosine is x”, because the length of the arc of the circle in radii is the same as the measurement of the angle in radians. Similarly, in computer programming languages the inverse trigonometric functions are usually called asin, acos, atan.
