Hey all, I have a system of differential equations that I want to solve using Runge Kutta, but for hte life of me I can't figure out the syntax for the command. Maybe someone here can point out where I am going wrong? > accx := m*(diff(x(t), `$`(t, 2))) = -q*A*sin(w*t)-q^2/(x(t)^2+y(t)^2); > accy := m*(diff(y(t), `$`(t, 2))) = -q^2/(x(t)^2+y(t)^2); > IC := x(0) = -0.1322943021e-8, y(0) = 0.793765813e-10, (D(y))(0) = 0, (D(x))(0) = 3839294.99; > RungeKutta([acc, acc2], IC, 0.1e-14);
