The cos() method is used to return the cosine of a specified angle expressed in radians or degrees which is in range [-inf, +inf]. The returned value is in range [-1, +1].
Syntax:
cos(angle)
Parameters: This method accepts a parameter as mentioned above and described below:
- angle: This parameter holds the specified angle in radians or degrees.
Return Value: This method returns the value in the range of -1 to +1.
Example 1:
Javascript
| <!DOCTYPE html><html>  <head>    <!-- Adding the FabricJS library -->    <script src=    </script></head>  <body>    <script type="text/javascript">          // Calling cos() function over         // specified angles of 0 and 5        console.log(fabric.util.cos(0));        console.log(fabric.util.cos(5));    </script></body>  </html> | 
Output:
1 0.28366218546322625
Example 2:
Javascript
| <!DOCTYPE html><html>  <head>    <!-- Adding the FabricJS library -->    <script src=    </script></head>  <body>    <script type="text/javascript">          // Specifying some angles        vara = -1;        varb = 0.6;          // Calling cos() function over        // above specified angles        console.log(fabric.util.cos(a));        console.log(fabric.util.cos(b));    </script></body>  </html> | 
Output:
0.5403023058681398 0.8253356149096783
