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

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

\frac{6}{( x ^{2} + 2 ) x ^{2} + 2}

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

3 \cdot \frac{1 \cdot x ^{2} + 2 - \frac{x}{x ^{2} + 2} x}{( x ^{2} + 2 ) ^{2}} : \frac{6}{( x ^{2} + 2 ) x ^{2} + 2}

= \frac{6}{( x ^{2} + 2 ) x ^{2} + 2}

\int \frac{11}{1 - x ^{2}} d x

\frac{d}{d x} (8 x^{2} sin (x) tan (x))

\frac{d y}{d x} = \frac{y ^{2} - y}{x}

x^{2} y^{^{''}} - 4 x y^{^{'}} + 6 y = 0, y (1) = 0.4, y^{^{'}} (1) = 0

y d x - (x + y) d y = 0
