The differential equation y" + b(x)y' + c(x)y = 0, x > 0 has a general solution given by y = C₁y1 + C2Y2, where y₁(x) = x and y₂(x) = xe³3x (a) Compute the Wronskian Wy1, y2). (b) Using the method of variation of parameters, we can compute a particular solution of the equation y" + b(x)y' + c(x)y 18xe 33x x > 0, by setting yp = u₁(x)y₁(x) + u₂(x)y₂(x). Compute u₂(x) if we know 3 that u₂(0) = 0.
