JavaScript TAN

The JavaScript TAN function is a Math function used to calculate the Trigonometry Tangent for the specified expression. The syntax of the JavaScript TAN Function is:

Math.tan(number);

The mathematical formula of the JavaScript Trigonometry Tangent function 

TAN(x) = Length of the Opposite Side / Length of the Adjacent Side

JavaScript TAN Function Example

In this example, We are going to find the JavaScript Tangent values of different data types and display the output

TIP: Please refer JavaScript ATAN Function to find the JavaScript Arc Tangent.

JavaScript TAN Function

TAN Function on the string value will return NaN

document.getElementById("Str").innerHTML = Math.tan("JavaScript");

JS TAN Math function on Null value returns Zero as output

document.getElementById("Null").innerHTML = Math.tan(null);
