expand (x^2+y^2)dx+(2xy+cos(y))dy

expand

(x^{2} + y^{2}) d x + (2 x y + cos (y)) d y

x^{2} d x + y^{2} d x + 2 x y d y + cos (y) d y

Solution steps

(x^{2} + y^{2}) d x + (2 x y + cos (y)) d y

Expand

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

= x^{2} d x + y^{2} d x + (2 x y + cos (y)) d y

Expand

d y (2 x y + cos (y)) : 2 x y d y + cos (y) d y

= x^{2} d x + y^{2} d x + 2 x y d y + cos (y) d y

2 (x - \frac{3}{2})

\frac{1}{( z + j ) ( z - j )}

(x + 1)^{2} + 4 y^{2} - arctan (\frac{x + 1}{2 y})

7 (2 x ln (x^{2} + 5) (x^{2} + 5) - 2 x^{3})

x^{2} + 2 x - 1 \cdot (x^{2} + 2 x - 1)
