In RPN mode:
In algebraic mode:
Answer: The area under Sin
shown in the Y level of the stack, in Figure 8 (assuming RPN mode).
Example 3: Integrate the function shown below from 0 to 2∏. Use FIX 4 as the display setting. Make sure the HP 35s
is in radians mode.
Solution: In either RPN or algebraic mode:
The display should look similar to the one shown in Figure 10.
