FN 6
: SINE
Example: FN 6: Q20 = SIN-Q5
Calculates and assigns the sine of an angle in
degrees (°)
FN 7
: COSINE
Example: FN 7: Q21 = COS-Q5
Calculates and assigns the cosine of an angle in
degrees (°)
FN 8
: ROOT SUM OF SQUARES
Example: FN 8: Q10 = +5 LEN +4
Calculates and assigns length from two values
FN 13
: ANGLE
Example: FN 13: Q20 = +25 ANG-Q1
Calculates the angle from the arc tangent of two
sides or from the sine and cosine of the angle (0° <
angle < 360°) and assigns it to a parameter
