In this problem we consider an equation in differential form M dx + N dy = 0. The equation (6x + 4x'y²) dx + (6x² - + 3)dy = 0 in differential form M dx + Ñ dy = 0 is not exact. Indeed, we have M, - N, = For this exercise we can find an integrating factor which is a function of y alone since M, - N, is a function of y alone. Namely we have (y) = Multiplying the original equation by the integrating factor we obtain a new equation M dx + N dy = 0 where M = N = Which is exact since M, N = are equal. This problem is exact. Therefore an implicit general solution can be written in the form F(x, y) = C where F(x, y) =
