soSo I am looking for a way to calculate and show dynamically as text the x-Axis-valuex-Axis-value
of the Intercept of those two curves.
Manipulate[Plot[s*(1 + r/12)^(y) + m*((1 + r/12)^y - 1)/(r/12), {y, 1, 36},
GridLines -> {None, {g}}, PlotRange -> {0, g*1.1},
GridLinesStyle -> Directive[Red, Thick],
AxesLabel -> {"Months", "Fr"},
PlotLabel -> "Saving Calculator"],
{{s, 100, "Inintial"Initial Savings"}, 0, 10000, 100, Appearance -> "Labeled"},
{{r, 0.05, "Interest Rate"}, 0, 0.1, 0.01, Appearance -> "Labeled"},
{{m, 50, "Monthly Savings"}, 0, 500, 10, Appearance -> "Labeled"},
{{g, 5000, "Saving Goal"}, 1000, 100000, 1000, Appearance -> "Labeled"}]
Any help would be much appreciated! Its about the intercept of the red to the blue curve.
