expand sqrt(1+x^2)dy+(x+y+sqrt(1+x^2))dx

expand

1 + x^{2} d y + (x + y + 1 + x^{2}) d x

1 + x^{2} d y + x d x + y d x + d x 1 + x^{2}

Solution steps

1 + x^{2} d y + (x + y + 1 + x^{2}) d x

= d y 1 + x^{2} + (x + y + 1 + x^{2}) d x

Expand

d x (x + y + 1 + x^{2}) : x d x + y d x + d x 1 + x^{2}

= 1 + x^{2} d y + x d x + y d x + d x 1 + x^{2}

\frac{d ^{2}}{d ^{2} x} (x y + 5 e^{y} = 5 e)

\frac{4.5805 ( z - 0.4776 )}{( z )}

40 (2 - 2)

(\frac{x}{3} + \frac{1}{6}) (\frac{1}{6} + \frac{2 y}{3})
