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 var a = -1; var b = 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
