Hello community I need to solve a complex set of equations using Mathematica and would like to know if you could help with the writing in the program. These are the equations that need to be written: dx/dt=-ax-bxy-dxz dy/dt=ax-by+cz-dxy dz/dt=by-cz-cxz d?/dt=dxy+exz where x,y,z,? are variables…

DSolve did not give solution: ClearAll[x, y, z, gamma, t, a, b, c, d, e]; eq1 = x'[t] == -a x[t] - b x[t] y[t] - d x[t] z[t]; eq2 = y'[t] == a x[t] - b y[t] + c z[t] - d x[t] y[t]; eq3 = z'[t] == b y[t] - c z[t] - c x[t] z[t]; eq4 = gamma'[t] == d x[t] y[t] + e x[t] z[t]; DSolve[{eq1, eq2, eq3, eq4…

Thank you Nasser. Is there any way to obtain a formula corresponding to this interpolated functions or plots?

Is there any way to obtain a formula corresponding to this interpolated functions or plots? I am no expert in this area, but the way I’ve seen it done is by getting the x,y values from the InterpolatingFunction object, then use InterpolatingPolynomial. InterpolatingFunction itself uses piecewi…
