expand (ysin(x)+xycos(x))dx+(xsin(x)+1)dy

expand

(y sin (x) + x y cos (x)) d x + (x sin (x) + 1) d y

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

Solution steps

(y sin (x) + x y cos (x)) d x + (x sin (x) + 1) d y

= (y sin (x) + y x cos (x)) d x + (x sin (x) + 1) d y

Expand

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

= y sin (x) d x + y x cos (x) d x + (x sin (x) + 1) d y

Expand

d y (x sin (x) + 1) : x sin (x) d y + d y

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

(x - h)^{2} + (y - k)^{2}

(cos (x) - sin (x) - 1)^{2}

\frac{1}{s ( s + 5 ) ^{3}}

2 x (2 x + 1)

\frac{8 x}{( x ^{2} + 4 ) ^{2}}
