kCoordinate Conversion (Pol (x, y), Rec (r, θ ))

•Calculation results are automatically assigned to vari- ables E and F.

•Example 1: To convert polar coordinates (r2,
60°) to rectangular coordinates (x, y) (Deg)

x  1	AF2 P60 T=
y  1.732050808	0o

•Press 0n to display the value of x, or 0 oto dis- play the value of y.

•Example 2: To convert rectangular coordinates (1, 3) to polar coordinates (r,
) (Rad)

r  2	f 1 P L3 T=
θ  1.047197551	0o

•Press 0 nto display the value of r, or 0o to dis- play the value of
.
