expand (2x-sin(y))dx+(-xcos(y))dy

expand

(2 x - sin (y)) d x + (- x cos (y)) d y

2 x d x - sin (y) d x - x cos (y) d y

Solution steps

(2 x - sin (y)) d x + (- x cos (y)) d y

Expand

d x (2 x - sin (y)) : 2 x d x - sin (y) d x

= 2 x d x - sin (y) d x + (- x cos (y)) d y

Remove parentheses:

(- a) = - a

= 2 x d x - sin (y) d x - x cos (y) d y

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

lo g_{10} (6) (x - 8)

\frac{3 ( x - 1 ) ^{2}}{2}

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

cos (x) sin (x) (1 + cos (x))
