operations.”
Function Soft key
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.
