Weby(x) = x+v(x) = x+1/w(x) or y(x) = x+ 5x c− x5. 4. Solve the following differential equations. (a) xy′ = p x2 +y2; (b) (1+x2)y′ + 2xy = 4x3. Solution (a) If we re–write the equation as y′ = p 1+ (y/x)2, we see that it is homogeneous. To solve, we set v = y/x. Then y(x) = xv(x) and y′ = xv′ + v. The differentiable equation ...

Web0 ≤ t ≤ 1. Solution. Set f x = 2xz +y2, (1) f y = 2xy, and (2) f z = x 2+3z . (3) Integrating the first equation with respect to x, we get f(x,y,z) = x 2z +xy +g(y,z). Therefore f y(x,y,z) = 2xy+g y(y,z), so comparing with equation (2), we find that g y(y,z) = 0. In other words, g(y,z) = h(z). Thus f(x,y,z) = x2z +xy2 +h(z), from which we ... Web2xy2 +2ydx = x2y2 +2xy +g(y) And check to see that f y = N: f y = 2x2y +2x+g0(y) = 2x2y +2x In this case, g0(y) = 0, and we don’t need to add g(y). The implicit solution: x 2y …
