expand (1+y^2)dx+(xy)dy

expand

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

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

Solution steps

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

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

Expand

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

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

Remove parentheses:

(a) = a

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

(a - b)^{2} + (c - d)^{2}

2 π^{r} (r + h)

3 (y + 2) d x

cos (2) (π + x)

\frac{1}{s ^{3} ( s - 1 )}
