expand (19y^2)dx-(20xy+y^2)dy

expand

(19 y^{2}) d x - (20 x y + y^{2}) d y

19 y^{2} d x - 20 y x d y - y^{2} d y

Solution steps

(19 y^{2}) d x - (20 x y + y^{2}) d y

= (19 y^{2}) d x - (20 y x + y^{2}) d y

Expand

- d y (20 x y + y^{2}) : - 20 y x d y - y^{2} d y

= (19 y^{2}) d x - 20 y x d y - y^{2} d y

Remove parentheses:

(a) = a

= 19 y^{2} d x - 20 y x d y - y^{2} d y

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

\frac{d}{d y} ((x) (x^{2} + sin (5 x)))

e l i p se (16 x^{2} - 4 x y + 16 y^{2} - 112 x - 136 y = 704)

\frac{1}{5} e^{x} (e^{x} - 1)
