## Differential Equation: (1-xy)^-2 dx + [y^2 + x^2 (1-xy)^-2] dy = 0

Hello, can anyone solve this equation?

I can't figure it out,

(1-xy)^-2 dx + [y^2 + x^2 (1-xy)^-2] dy = 0

Thanks.

## Differential Equation: y' = x^3 - 2xy, where y(1)=1 and y' = 2(2x-y) that passes through (0,1)

Can anyone solve this D. E.?

y' = x^3 - 2xy, where y(1)=1

and

y' = 2(2x-y) that passes through (0,1)

## Applications Of Differential Equations

The radial stress *p* at distance r for the axis of the thick cylinder subjected to internal pressure is given by p + r (dp/dr) = A − p where *A* is a constant. If p = p_{0} at the inner wall r = r_{1} and is negligible (p = 0) at the outer wall r = r_{2} find an expression for p.
