expand (1-cos(x))dx-(1-cos(y))dy

expand

(1 - cos (x)) d x - (1 - cos (y)) d y

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

Solution steps

(1 - cos (x)) d x - (1 - cos (y)) d y

Expand

d x (1 - cos (x)) : d x - cos (x) d x

= d x - cos (x) d x - (1 - cos (y)) d y

Expand

- d y (1 - cos (y)) : - d y + cos (y) d y

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

\frac{1}{cos ( x ) ( sec ( x ) - tan ( x ) )}

\frac{4}{( x ^{2} + x ) ( x + 3 ) ( x ^{2} + 4 ) ( x + 2 ) ( x + 4 )}

- \frac{( 2 - x ) ^{2}}{4}

\frac{y u ^{2}}{u ∣ u ∣}

cos (0.2)
