(\partial)/(\partial x)(x/(sqrt(x^2+y^3)))

\frac{\partial}{\partial x} (\frac{x}{x ^{2} + y ^{3}})

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

Solution steps

\frac{\partial}{\partial x} (\frac{x}{x ^{2} + y ^{3}})

Treat

y

as a constant

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{\partial}{\partial x} ( x ) x ^{2} + y ^{3} - \frac{\partial}{\partial x} ( x ^{2} + y ^{3} ) x}{( x ^{2} + y ^{3} ) ^{2}}

\frac{\partial}{\partial x} (x) = 1

\frac{\partial}{\partial x} (x^{2} + y^{3}) = \frac{x}{x ^{2} + y ^{3}}

= \frac{1 \cdot x ^{2} + y ^{3} - \frac{x}{x ^{2} + y ^{3}} x}{( x ^{2} + y ^{3} ) ^{2}}

Simplify

\frac{1 \cdot x ^{2} + y ^{3} - \frac{x}{x ^{2} + y ^{3}} x}{( x ^{2} + y ^{3} ) ^{2}} : \frac{y ^{3}}{( x ^{2} + y ^{3} ) x ^{2} + y ^{3}}

= \frac{y ^{3}}{( x ^{2} + y ^{3} ) x ^{2} + y ^{3}}

y^{^{'}} + 7 = e^{7 x + y - 5}, y (0) = 5

n = 0 \sum \infty \frac{n + 2}{n + 1}

\frac{1}{4} x^{2} - 1, 0, 2, 8

\int_{0}^{2} \frac{1}{( x - 1 ) ^{2}} d x

y = 2 sin (x)
