The ACOS function in ProBuilder language is used to calculate the arc cosine of a given value. The arc cosine is the inverse of the cosine function, which means it returns the angle whose cosine is the specified number. This function is particularly useful in various technical calculations where angle determination is required based on the cosine value.

Syntax:

ACOS(value)

Example:

Suppose you want to find the angle in radians for a cosine value of 0.5. You can use the ACOS function as follows:

angle = ACOS(0.5)

This will assign the value of the angle, in radians, whose cosine is 0.5 to the variable angle.

Additional Information:

• The value parameter must be between -1 and 1, inclusive. Values outside this range will result in an error.
• The result of the ACOS function is in radians. To convert it to degrees, you can multiply the result by 180/pi.
• This function is commonly used in trigonometric calculations that are pivotal in geometric transformations and in analyzing periodic functions.

Understanding the ACOS function and its output in radians is crucial for effectively implementing trigonometric calculations in your ProBuilder scripts.
