How to Use Tan Method in TypeScript

tan() Method in TypeScript

  • The tan() method of the Math object is used to get the tangent of a number.
  • In the tan() method, the numeric value represents the tangent of the angle.
Syntax
  1. Math.tan(number);   
The following example shows how to use the tan() method and it returns the tangent of numbers in radians. We use the following steps to use this method.
 
Step 1
 
Open Visual Studio 2012 and click "File" -> "New" -> "Project...". A window is opened. Give the name of your application as "tangent" and then click ok.
 
Step 2
 
After this session the project has been created; your new project should look like this:
