Hi i am new to mathematica, i have tried to combine this simple
problem of showing a Reaction speed but i cannot plot the tangent line
on a plot, and i don't seem to be able to have my regression in the
same notebook
data = {{0, .005}, {100, .00465}, {200, .00432}, {400, .00374}, {600,
\
.00323}, {900, .00260}, {1200, .00209}, {1500, .00168}};
N2O5 = Exp[Fit[data /. {x_, y_} -> {x, Log[y]}, {1, x}, x]] //
Simplify (*not in same notebook as the rest*)
f[x_] := 0.00499929 E^(-0.000726892 x) (*this works*)
g=B4[x_] := -3.63394*10^-6 E^(-0.000726892 x) (*this works*)
Plot[0.00499929 E^(-0.000726892 b), {b, 0, 4000},
PlotRange -> {0, .006}](*this works*)
Show[Plot[0.00499929 E^(-0.000726892 x), {x, -1000, 4000}],
ListPlot[data, PlotRange -> {0, .006}, PlotStyle -> {Red}]] (*this
works*)
Manipulate[
Solve[g=B4[x0]*{x - x0} + f[x0] == y], {x0, 0, 1500, 1, Appearance ->
"Labeled"}] (*this works*)
But i cannot combine it together, not even this small thing
Manipulate[
Plot[y /. Solve[g\.b4[x0]*{x - x0} + f[x0] == y], {x0, 0, 1500, 1,
Appearance -> "Labeled"}], {x, 0, 4000}, PlotRange -> {0, .006}]
Please help me, thanks
