- Arguments
`[n]`

- Docstring
The inverse of cos, returns the arc cosine of a value. This function expects the values in the range of -1 to 1 and values are returned in the range 0 to Math/PI (3.1415927).

- Works only inside sketch functions?
- No
- Original Processing method
- acos()

- Arguments
`[n]`

- Docstring
The inverse of sin, returns the arc sine of a value. This function expects the values in the range of -1 to 1 and values are returned in the range -PI/2 to PI/2.

- Works only inside sketch functions?
- No
- Original Processing method
- asin()

- Arguments
`[n]`

- Docstring
The inverse of tan, returns the arc tangent of a value. This function expects the values in the range of -Infinity to Infinity (exclusive) and values are returned in the range -PI/2 to PI/2 .

- Works only inside sketch functions?
- No
- Original Processing method
- atan()

- Arguments
`[y x]`

- Docstring
Calculates the angle (in radians) from a specified point to the coordinate origin as measured from the positive x-axis. Values are returned as a float in the range from PI to -PI. The atan2 function is most often used for orienting geometry to the position of the cursor. Note: The y-coordinate of the point is the first parameter and the x-coordinate is the second due to the structure of calculating the tangent.

- Works only inside sketch functions?
- No
- Original Processing method
- atan2()

- Arguments
`[angle]`

- Docstring
Calculates the cosine of an angle. This function expects the values of the angle parameter to be provided in radians (values from 0 to Math/PI*2). Values are returned in the range -1 to 1.

- Works only inside sketch functions?
- No
- Original Processing method
- cos()

- Arguments
`[radians]`

- Docstring
Converts a radian measurement to its corresponding value in degrees. Radians and degrees are two ways of measuring the same thing. There are 360 degrees in a circle and (* 2 Math/PI) radians in a circle. For example, (= 90Â° (/ Math/PI 2) 1.5707964). All trigonometric methods in Processing require their parameters to be specified in radians.

- No
- Original Processing method
- degrees()

- Arguments
`[degrees]`

- Docstring
Converts a degree measurement to its corresponding value in radians. Radians and degrees are two ways of measuring the same thing. There are 360 degrees in a circle and 2*PI radians in a circle. For example, 90Â° = PI/2 = 1.5707964. All trigonometric methods in Processing require their parameters to be specified in radians.

- Original Processing method
- radians()

- Arguments
`[angle]`

- Docstring
Calculates the sine of an angle. This function expects the values of the angle parameter to be provided in radians (values from 0 to 6.28). A float within the range -1 to 1 is returned.

- Works only inside sketch functions?
- No
- Original Processing method
- sin()

- Arguments
`[angle]`

- Docstring
Calculates the ratio of the sine and cosine of an angle. This function expects the values of the angle parameter to be provided in radians (values from 0 to PI*2). Values are returned in the range infinity to -infinity.
