Integrate e^6y.y^2 dy |
|
Answer» Step-by-step explanation: M∂y = ∂2I∂y ∂X ∂N∂x = ∂2I∂y ∂x they end up the same! And so this will be true: ∂M∂y = ∂N∂x When it is true we have an an "exact equation" and we can proceed. And to DISCOVER I(x, y) we do EITHER: I(x, y) = ∫M(x, y) dx (with x as an independent VARIABLE), OR I(x, y) = ∫N(x, y) dy (with y as an independent variable) And then there is some extra work (we will show you) to arrive at the general solution I think it had helped you |
