Below is the example of the Math cos() Method.
document.write("The cos of 0 : " + Math.cos(0));
The cos of 0 : 1
The Math.cos() method is used to return the cosine of a number. The Math.cos() method returns a numeric value between -1 and 1, which represents the cosine of the angle given in radians. The cos() is a static method of Math, therefore, it is always used as Math.cos(), rather than as a method of a Math object created.
Parameters: This function accepts single parameter as mentioned above and described below:
- value: This parameter is a number given in radians.
Returns: The Math.cos() function returns the cosine of the given numbers which range from -1 to 1.
- Example 1:
Input: Math.cos(010) Output : -0.14550003380861354
- Example 2:
Input: Math.cos(10) Output : -0.8390715290764524
More codes for the above method are as follows:
Program 1: When 1 is passed as a parameter.
Result : 0.5403023058681398
Program 2: When PI is passed as a parameter.
Result : -1
