Compound Interest - Casio FX-CG10 Software User's Manual

• An error occurs if parameters are not configured correctly.
Use the following function menus to maneuver between calculation result screens.
• { REPEAT } ... {parameter input screen}
• { GRAPH } ... {draws graph}
After drawing a graph, you can press !1(TRACE) to turn on trace and read calculation
results along the graph.
Each press of e while trace is turned on cycles the displayed value in the sequence: present
