This is a detailed tutorial of the NumPy Trigonometric Universal Functions. Learn the usage of these functions with the help of examples.

### Trigonometric Functions

Trigonometric Functions are real functions that have a relation of the angle of a right-angled triangle to ratios of two side lengths. The trigonometric functions which are very common at use are sine, cosine and tangent. And the reciprocal of these functions is cosecant, secant and cotangent.

So NumPy provides us with some of the Unfuncs with the help of which we can calculate the trigonometric functions. The function is as follows: `sin()` , `cos()` and `tan()`which will take values in radians and give us corresponding values.

Let us take an example to have a better understanding:

In the trigonometric function in the NumPy, radians are taken as values by default, but we can convert them into the degree. As radian is pi/180*degree, this is how they are related to each other.

let us take an example to understand it better:
