expand (x+cos(y))dx+(-xsin(y))dy

expand

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

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

Solution steps

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

Expand

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

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

Remove parentheses:

(- a) = - a

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

(e^{x} + 2)^{5}

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

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

\frac{2 s ^{2} + 4 s + 5}{s ( s + 1 )}

\frac{1}{( x - 1 ) ( x + 3 )}
