I have to solve a series of differential equations along with a constraint that has to be satisfied at each point of time. To solve the differential equations, I first solves the following in order to obtain ?(t) and x(t) sol1 = NDSolve[{?'[t]...
I have the following system of differential equations $$\rho1(t) = {(c1-\lambda(t))\over 2k1} $$ $$\dot\lambda(t)={\beta \lambda(t)-{(c1-\lambda(t))^2\over 4k1}}$$ and $$\rho2(t) = {(c2-x(t))\over 2k2} $$ $$\dot x(t) ={\beta x(t)-\delta1...
