Show that by making the substitution

Show that the solution of this equation is v = 1 + Ce^–t and hence find x(t). This technique is a standard method for solving second-order differential equations in which the dependent variable itself does not appear explicitly. Apply the same method to obtain the solutions of the differential equations

V = d.x dt the equation dx dt ap + dx dt may be expressed as = 1 - + v = 1 dt
