This operator is used to calculate the sine of a number
given in radians or degrees (see the
command). If "
" and "
" are coordinates of a point
a
b
on a circle of radius "
r
", then the angle of measure "θ"
can be defined by the equation:
If a value is given in radians and a conversion is
needed to degrees, use the formula: 360° = 2π
radians.

x
Syntax:
VARx=SIN(r) where "x" is the numeric variable number and "r" is a value provided in either degrees or
radians based on the RADIAN command. Parentheses ( () ) must be placed around the SIN operand. The
result will be specified to 5 decimal places.
Example:

VAR1=5 * SIN(PI/4)
; Set variable 1 equal to 5 times the sine of Pi divided by 4
