Practice solving numeric integration problems

Example 1: Integrate the function 1/X from 1 to 10. Use FIX 4 as the display setting.
Solution: In either RPN or algebraic mode: ¹
The display should look similar to the one shown in Figure 1. Note, if you have other equations already in
the HP 35s calculator, the top line of the display may not indicate "3*3 lin. solve" but may show another
equation.
To show the checksum and length of this equation, press the following in RPN or algebraic mode
In RPN or algebraic mode: ¹
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:
Now enter the lower and upper limits of the integration.
In RPN mode:
In algebraic mode:
Integrate the function using X as the variable of integration.
