C++ Math cos()
The function is used to find the cosine of an angle expressed in terms of radian.
Consider a radian 'x'. Syntax would be:
Note: If the value passed is an integer type, then it is cast to double.
x: Value specified in terms of radian.
It returns the cosine of an angle in the range of[-1,1].
Let's see a simple example when the value of x is positive.
Cosine of an angle is : 0.50046
In this example, cos() function calculates the cosine of an angle when the degree is equal to 60.
Let's see a simple example when the value of x is negative.
Cosine of an angle is :0.000796327
In this example, cos() function finds the cosine of an angle when the value is negative but it remains the same as cos(-x) =cos(x).
