hello,
i am a new user of mathematica,i need to turn on an algorithm in which i have to solve differential equations and manipulate some parameters. when i use DSolve and plotparametric it work but if i use the same thig in manipulate block i have an error of integration!!
Manipulate[
sol = DSolve[thetaprime'[t] == ki[t],
i'[t] == -kthetaprime[t] - ri[t] + 10, i[0] = 0,
thetaprime[0] = 0 {i, thetaprime}, t]
ParametricPlot[
Evaluate[{i[t], thetaprime[t]} /. sol, [t, 0, 7]]], {r, 1, 2}, {k,1, 2}]
another problem that i need to use the steepest descent method but i want to put it in a loop and modify the point of departure x0 and the step at each iteration but i don't know how.
thank you in advance for uour help
regards!
