Show that x(t) = t + 4 is a solution of the differential equation sin(t)d3x + 4dx x = t. Solution: sin(t)d3x + 4dx x = 0 + 4 1 (t + 4) = t: write sin(t)d3x + 4dx x = t as a system of differential equations. Solution: write x1 = x, x2 = x , x3 = x to get x . 1 sin t x2 t sin t or. Give one solution to the system in vector form.
