REMARKS

* This is one of the few functions that does not require any arguments.
* You must include the empty parentheses after the function name.
* This constant is used to calculate the area of a circle.
* You can use the COS function to return the cosine of an angle.
* You can use the SIN function to return the sine of an angle.
* You can use the TAN function to return the tangent of an angle.
* You can use the SEC function to return the secant of a number.
* You can use the CSC function to return the cosecant of a number.
* You can use the COT function to return the cotangent of a number.
* You can use the SQRTPI function to return the square root of a number multiplied by PI.
