Is an angle in radians.

Calculating the Cotangent of an Angle

The following request calculates the cotangent of PI/2 and PI/4 radians. 

DEFINE FILE ggsales

PI2 = PI()/2;

PI4 = PI()/4;

END



TABLE FILE ggsales

PRINT COMPUTE

COTGENT2 = COT(PI2);

COTGENT3 = COT(PI4);

BY DATE

The output is shown in the following image.

COT calculates the cotangent of PI/2 radians.

COT(1.57)

The result is 0 (zero).
