expand x(1+y^2)dx-y(1+x^2)dy

expand

x (1 + y^{2}) d x - y (1 + x^{2}) d y

x d x + x y^{2} d x - y d y - x^{2} y d y

Solution steps

x (1 + y^{2}) d x - y (1 + x^{2}) d y

Expand

x d x (1 + y^{2}) : x d x + x y^{2} d x

= x d x + x y^{2} d x - y (1 + x^{2}) d y

Expand

- y d y (1 + x^{2}) : - y d y - x^{2} y d y

= x d x + x y^{2} d x - y d y - x^{2} y d y

\frac{d}{d s} ((z) (3 x^{2} + y^{2} + 2 z^{4} - 10))

\frac{2 s + 1}{( s ^{2} + 1 ) ( s - 1 ) ( s - 2 )}
