(\partial)/(\partial x)(sqrt((x+5)/(y+4)))

\frac{\partial}{\partial x} (\frac{x + 5}{y + 4})

\frac{1}{2 x + 5 y + 4}

Solution steps

\frac{\partial}{\partial x} (\frac{x + 5}{y + 4})

Treat

y

as a constant

Apply the chain rule:

\frac{1}{2 \frac{x + 5}{y + 4}} \frac{\partial}{\partial x} (\frac{x + 5}{y + 4})

= \frac{1}{2 \frac{x + 5}{y + 4}} \frac{\partial}{\partial x} (\frac{x + 5}{y + 4})

\frac{\partial}{\partial x} (\frac{x + 5}{y + 4}) = \frac{1}{y + 4}

= \frac{1}{2 \frac{x + 5}{y + 4}} \cdot \frac{1}{y + 4}

Simplify

\frac{1}{2 \frac{x + 5}{y + 4}} \cdot \frac{1}{y + 4} : \frac{1}{2 x + 5 y + 4}

= \frac{1}{2 x + 5 y + 4}

\int \frac{1}{9 x ^{2} + 1} d x

\int sin (d) x d x

\frac{d}{d x} (\frac{x ^{3} + 1}{x ^{3} - 1})

\int (x - 1) 2 - x d x

x \to 3 lim (\frac{f ( x ) - f ( π )}{x - 3})
