IRCP Function: Reciprocal 1/x DBl Remarks: Returns the reciprocal of the numeric argument. Function: RCP 4 ~ I REC 0.25 ~ I (r,e) (x,y) Function: Polar to rectangular coordinate conversion SNG Remarks: Converts numeric arguments of polar coordinates to their rectangular coordinate equivalents. The first argument indicates the distance from the origin and the second argument the angle. The angle depends on the mode (DEG, RAD or GRAD) . The converted values indicate the distances from the y-axis and the x-axis, and are assigned to the fixed variables Y and Z, respectively. Example: DEGREE 1ENTER I REC (12,30) IENTER I Z IENTER I 10.39230485 (x =: 10.4) 6 (y = 6) I*RND Function: Random number DBl Remarks: See RND and RANDOMIZE in the BASIC COMMAND DICTIONARY. I ROT xrvl Function: xth root DBl Remarks: Returns the xth root of the argument y. Enter as y ROT x. Example: 7776 ROT 5 IENTER I 6 96 I*SGN Function: Sign of argument Remarks: Returns a value based on the sign of the argument. If x > 0, the function returns 1. If x < 0, the function returns -1. If x = 0, the function returns O. DBl ISIN Function: Sine sin x DBl Remarks: Returns the sine of the angle argument. The value returned depends on the mode (DEG, RAD or GRAD). Example: DEGREE 1ENTER I SIN 30 IENTER I 0.5 ISQR ~I Function: Square root DBl Remarks: Returns the square root of the argument. Example: SOR 3 IENTER I 1.732050808 ISQU Function: Square DBl Remarks: Returns the square of the argument. Example: SOU 41 ENTER I 16 97

Function:
Polar to rectangular coordinate conversion
SNG
Remarks:
Converts numeric arguments of polar coordinates to their
rectangular coordinate equivalents.
The
first argument indicates the distance from the origin
and the second argument the angle.
The
angle depends on
the mode (DEG, RAD
or
GRAD). The converted values
indicate the distances from the y-axis and the x-axis, and
are assigned to the fixed variables Y and
Z,
respectively.
