standard.C.math.tan

Name Version Deprecated
tan version 1.0 no

Prototype:
number tan(number angle)

Parameters:
angle      [in] The angle in radians

Description:
Calculate the tangent of the specified angle.
The angle must be in radians. Multiply by M_PI/180 to convert degrees to radians.

Example:
import standard.C.math


class Main {
function Main() {
var angle;
var radians;
var result;

// Calculate the tangent of 30 degrees.
angle = 30;
radians = angle * M_PI/180;
result = tan(radians);
echo "The tangent of 30 degrees is " + result + ".\n";

// Calculate the arctangent of the previous tangent.
radians = atan(result);
angle = radians * 180/M_PI;
echo "The previous tangent is equivalent to " + ceil(angle) + " degrees.\n";
}
}


Results
The tangent of 30 degrees is 0.57735026918962573.
The previous tangent is equivalent to 30 degrees.

Returns:
the tangent of the specified angle
