To use degrees as inputs for trigonometric tools, the values need to be converted into radians. To do the conversion, multiply the input values by pi/180, or approximately 0.01745.
In Python, this conversion can be done directly in the expression, or you can define a variable to store the value once and reuse it as needed. Using the Cos tool as an example, the syntax could be in the following form:
Or, you can use a variable for the conversion factor:
The following illustrations demonstrate converting inputs whose values are in degrees into radians before performing the particular operation.
Note:
The variable defined in the example above will be used in these examples.
