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

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.

Integrating an Equation

1. Key in an equation. (see "Entering Equations into the Equation List" in chapter
6) and leave Equation mode.
2. Enter the limits of integration: key in the lower limit and press
in the upper limit.
