Set the calculator to DEC mode when computing with complex numbers.
q $ $ $ Selects the REAL menu. Use ! and o" to scroll with in the REAL menu
to highlight the desired complex results format a+bi , or r ±q, and press <.
, a+bi , or r ±q set the format of complex number results.
REAL
rectangular complex results
a+bi
r ±q polar complex results
Notes:
• Complex results are not displayed unless complex numbers are entered.
• To access i on the keypad, use the multi-tap key g.
• Variables x , y , z , t , a , b , c , and d are real or complex.
• Complex numbers can be stored.
• Complex numbers are not allowed in data, matrix, vector, and where complex
arguments are not valid. A function can be defined with a complex number
expression and will calculate on the home screen and not in table.
• For conj(, real(, and imag(, the argument can be in either rectangular or polar
form. The output for conj( is determined by the mode setting.
• The output for real( and imag( are real numbers.
• Set mode to DEGREE or RADIAN depending on the angle measure needed.
