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

expand

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

x d x - y d x + x d y + y d y

Solution steps

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

Expand

d x (x - y) : x d x - y d x

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

Expand

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

= x d x - y d x + x d y + y d y

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

(x - 1 + x^{2})^{2}

(cos (4 t) + cos (3 t))^{2}

(1 - 3 y i)^{2}

3 (x + Δ x)
