HP 33S Solving numeric integration problems
The display should look similar to the one shown in Figure 1. Note, if you have other equations already in
the HP 33S calculator, the top line of the display may not indicate "EQN LIST TOP" but may show another
equation.
Figure 1
To show the checksum and length of this equation, press the following in RPN or algebraic mode. Note that
the symbol Õ means to press the right arrow direction of the cursor key at the top of the HP 33S.
In RPN or algebraic mode: ¹uÕϺÎ

If the checksum of the equation just entered does not equal B3AA, then you have not entered it correctly.
To exit equation mode, press:
In RPN or algebraic mode: ºd
Now enter the lower and upper limits of the integration.
In RPN mode: 1Ï10ºd
In algebraic mode: 1w10ºd
(Note: At this point, use the Ø or × keys to scroll through the equation list and make sure the
equation is displayed as shown in Figure 3 below). Note, if you have other equations already in the HP 33S
calculator, the top line of the display may not indicate "EQN LIST TOP" but may show another equation.
