Integrating An Equation; Operations With Complex Numbers - HP 35s User Manual

Scientific calculator.

The value of X-, Y-, Z-, T-register in ALG mode is the same in RPN mode. After
normal calculation, solving, programming, or integrating, the value of the four
registers will be the same as in RPN or ALG mode and retained when you switch
between ALG and RPN logic modes.
