C++ Math tan()

The function finds the tangent of an angle specified in terms of radian.

Syntax

Consider a radian 'x'. Syntax would be:

Note: If the value passed is an integral type, then it is cast to double.

Parameter

x: The value given in radian.

Return value

It returns the tangent of an angle given in radian.

Example 1

Let's see the simple example when the value of x is positive.

Output:

Tangent of an angle is : 0.176236

In this example, tan() function calculates the tangent of an angle when the value of degree is equal to 10.

Example 2

Let's see the simple example when the value of degree is negative.

Output:

Tangent of an angle is :-1.72993 

In this example, tan() function calculates the tangent of an angle when the value of degree is negative i.e -60.
