Can you do it without a calculator? Or are you relying on the calculator being a brain substitute? You calculator supports polar entry of complex numbers. Converting your expression above to polar is trivial Magnitude = e^0.00931 Angle = 0.3730 radians Look at your owner's manual for how to enter the values: http://support.casio.com/storage/en/manual/pdf/EN/004/fx-115_991ES_PLUS_C_EN.pdf Look on page 25.
