The java.lang.StrictMath.cos() is an inbuilt method in Java which is used to return the cosine value of a given angle. The method returns NaN when the given argument is NaN or infinity.
public static double cos(double num)
Parameters: The method accepts one parameter num of double type and refers to the angle in radian whose cosine value is to be returned.
Return Value: The method returns the cosine of the argument.
Input: num = 62.0 Output: 0.6735071623235862 Input: num = 64.6 Output: -0.19607204956188945
Below programs illustrate the java.lang.StrictMath.cos() method:
The cosine of 0.0 = 1.0 The cosine of 1.0 = 0.5403023058681398 The cosine of 64.6 = -0.19607204956188945
The cosine of -62.0 = 0.6735071623235862 The cosine of 1.0 = 0.5403023058681398 The cosine of 0.7853981633974483 = 0.7071067811865476
