HP 33S Solving numeric integration problems
Now view the uncertainty of the result.
In RPN mode: Å
In algebraic mode: <
Figure 5
Answer: The area under the 1/X curve from 1 to 10 is approximately 2.3026. Figure 5 shows the uncertainty of the
result assuming algebraic mode. In RPN mode, the uncertainty is shown in the second level of the stack.
Example 2: Integrate the function Sin
2
(X) from 0 to ∏. Use FIX 4 as the display setting. Make sure the HP 33S is in
radians mode.
Solution: In either RPN or algebraic mode: Þ14Ý2
ºdkhXº|)2Ï
Note: It is possible to write the equation using the = function, but the equation displayed using the )
function is may be clearer to read. The display should look similar to the one shown in Figure 6.

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 C615, 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: 0Ϻjºd
In algebraic mode: 0wºjºd
