7-4After drawing a graph, you can press !1(TRACE) to turn on trace and read calculationresults along the graph.Each press of e while trace is turned on cycles the displayed value in the sequence: presentvalue (PV) → simple interest (SI) → simple future value (SFV). Pressing d cycles in thereverse direction.Press J to return to the parameter input screen.3. Compound InterestThis calculator uses the following standard formulas to calculate compound interest.u PV, PMT, FV, nI % ≠ 0PMT = PV + × FVβα–FV =βαPV + × PMT– n =log (1+ iS) × PMT – FV × i(1+ iS) × PMT + PV × i{ }log (1+ i)I % = 0PV = (PMT × n + FV ) PMT = – nPV + FVFV = (PMT × n + PV) n = PMTPV + FV–= (1+ i × S) × , = (1 + i)i1 – –nβ βα0 .........Payment : End(Setup Screen)1 .........Payment : Begin(Setup Screen)i =100I%I%(1+ ) –1C/YP/Y100 × [C/Y ]...............................
