expandir (2x-1)dx+(3y+7)dy

Solução

expandir

(2 x - 1) d x + (3 y + 7) d y

2 x d x - d x + 3 y d y + 7 d y

Passos da solução

(2 x - 1) d x + (3 y + 7) d y

Expandir

d x (2 x - 1) : 2 x d x - d x

= 2 x d x - d x + (3 y + 7) d y

Expandir

d y (3 y + 7) : 3 y d y + 7 d y

= 2 x d x - d x + 3 y d y + 7 d y

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

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

(x - x y) d y

e^{x} (x + 2)

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