Hi , is there any one can tell me, how to convert from polar to rectangle and vice versa in fx-991 es calculator ??

Hi there, try this:-

for polar->rectangular
Shift' /> (Rec) [r value] [θ value] EXE' /> (=)
x result will also be stored in x variable memory, and y result in y.

for rectangular->polar
Shift' /> (Pol) [x value] [y value] EXE' /> (=)
r result will also be stored in x variable memory, and θ result in y.

Hope this helps.
