Math.tan() Method

Math.tan() Method is used to return the tangent of a number (angle). The tan method returns a numeric value that represents the tangent of the angle.

Syntax:

Math.tan(x)

Example:

<script>
    var one = Math.tan(90);
    document.writeln('Output of 90 : ' + one + '</br></br>');
    var two = Math.tan(45);
    document.writeln('Output of 45 : ' + two + '</br></br>');
    var three = Math.tan(30);
    document.writeln('Output of 30 : ' + three + '</br></br>');
    var four = Math.tan(Math.PI/45);
    document.writeln('Output of Math.PI/45 : ' + four + '</br></br>');
</script>

Output:

Output of 90 : -1.995200412208242

Output of 45 : 1.6197751905438615

Output of 30 : -6.405331196646276

Output of Math.PI/45 : 0.06992681194351041
