Differential and Integration Calculations
Example 1:
If a ball is dropped from a height of 100 meters, how far will it have
fallen after three seconds?
• Use a 9.8 meters per second per second for gravitational
acceleration, and disregard air friction.
Perform the following calculation:
Select the integration function from the menu that appears when you
select {CALC} on the option (OPTN) menu.
