Using a Command to Specify the Calculation
Result Format
Either of two special commands (
r∠θ or a+bi) can be input at the end
of a calculation to specify the display format of the calculation results.
The command overrides the calculator's complex number format setting.
Example: √
2 + √2i = 2∠45, 2∠45 = √2 + √2i (MthIO-MathO) (Angle unit:
Deg)
2 2 (i) (CMPLX)
( r∠θ)
2∠45
2 (∠) 45 (CMPLX) ( a+bi) √2+√2i
Statistical Calculations (STAT)
To start a statistical calculation, perform the key operation
(STAT)
to enter the STAT Mode and then use the screen that appears to select the
type of calculation you want to perform.
