Integration and Differential Equations
howellkb.uah.edu › public_html › DEtext24 Integration and Differential Equations So equation (2.2) is directly integrable.! Example 2.2: Consider the equation x2 dy dx − 4xy = 6 . (2.3) Solving this equation for the derivative: x2 dy dx = 4xy + 6 ֒→ dy dx = 4xy +6 x2. Here, the right-hand side of the last equation depends on both x and y, not just x . So equation (2.3) isnot directly integrable.
