Hello, I need to solve numerically an equation of the form v(t) = k1*z(t)*w(t)k2*i(t)k3*di(t)/dt The issue is that rungekutta methods are useful for solving di(t)/dt = 1/k3 * [ k1*z(t)*w(t)k2*i(t)k3*v(t) ] but I need to solve for v(t) What I did was: v (t) = k1*z(t)*w(t)k2*i(t)k3*[i(t)i(t1)]/h But is not a good approximation because the step size h cannot be small enough. I need a more sophisticated method than directly applying the difference quotient as I did. Thanks a lot!
