Function Soft key
FN6: SINE
Example FN6: Q20 = SIN–Q5
Calculates and assigns the sine of an angle in degrees
(°)
FN7: COSINE
Example FN7: Q21 = COS–Q5
Calculates and assigns the cosine of an angle in
degrees (°)
FN8: ROOT SUM OF SQUARES
Example: FN8: Q10 = +5 LEN +4
Calculate and assign length from two values.
FN13: ANGLE
Example: FN13: 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.
