expand (x^2-2y)dx+(2xy-3x^2)dy

expand

(x^{2} - 2 y) d x + (2 x y - 3 x^{2}) d y

x^{2} d x - 2 y d x + 2 x y d y - 3 x^{2} d y

Solution steps

(x^{2} - 2 y) d x + (2 x y - 3 x^{2}) d y

Expand

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

= x^{2} d x - 2 y d x + (2 x y - 3 x^{2}) d y

Expand

d y (2 x y - 3 x^{2}) : 2 x y d y - 3 x^{2} d y

= x^{2} d x - 2 y d x + 2 x y d y - 3 x^{2} d y

2 cos (t) (3 - 7 tan (t))

\frac{20}{( x - 1 ) ( x + 1 )}

- 6 \cdot (x + y + z)^{2}

4 (4 - π)

(x y + 1) d x + (x y - 1) d y
