DE exact equations: (3 + y + 2y^2 sin^2 x) dx + (x + 2xy - y sin 2x) dy = 0 |
|
DE Order one: (xy^2 + x - 2y + 3) dx + x^2 ydy = 2(x + y) dy |
|
DE: $(x²+4) y' + 3 xy = x$ |
|
DE: $x \, dx + [ sin^2 (y/x) ](y \, dx - x \, dy) = 0$ |
|
DE: 2xy dx + (y^2 + x^2) dy = 0 |
|
DE: 2xy dx + (y^2 - x^2) dy = 0 |
