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
