StrictMath tan() Method in Java
The java.lang.StrictMath.tan() is an in-built function in Java which returns the trigonometric tangent of an angle.
Syntax:
public static double tan(double ang)
Parameters: This function accepts a single parameter ang which is a double variable representing an angle (in radians) whose trigonometric tangent is to be returned by the function.
Return Value: This method returns the tangent of the angle passed as argument to the function. It gives rise to special cases:
- The method returns NaN if the argument is NaN or an infinity.
- The result is zero with the same sign as the argument, if the argument is zero.
Examples:
Input : ang = 0.5235987755982988(30 degree)
Output : 0.5773502691896257
Input : ang = 0.7853981633974483(45 degree)
Output : 0.9999999999999999
Below programs illustrate the java.lang.StrictMath.tan() function in Java:
Program 1:
import java.io.*;
import java.math.*;
import java.lang.*;
class GFG {
public static void main(String[] args)
{
double ang = ( 60 * Math.PI) / 180 ;
System.out.println( "tangent value of 60 degrees : "
+ StrictMath.tan(ang));
}
}
|
Output:
tangent value of 60 degrees : 1.7320508075688767
Program 2:
import java.io.*;
import java.math.*;
import java.lang.*;
class GFG {
public static void main(String[] args)
{
double ang = 77.128 ;
double rad = StrictMath.toRadians(ang);
System.out.println( "tangent value of 77.128 degrees : "
+ StrictMath.tan(rad));
}
}
|
Output:
tangent value of 77.128 degrees : 4.376055350774854
