Syntax:

double java.lang.StrictMath.atan(double a)

This method takes one argument of type double as its parameter. This method returns the arc tangent of a value; the returned angle is in the range -pi/2 through pi/2.

Special cases:

1. If the argument is NaN, then the result is NaN.

2. If the argument is zero, then the result is a zero with the same sign as the argument.

Parameters: One parameter is required for this method.

Approach

Java

public class StrictMathatan {
    public static void main(String[] args) {

        double a = 0.45;
        System.out.println(StrictMath.atan(a));
    }
}

Output:
