\frac{d}{d x} (\frac{x y}{x ^{2} + y ^{2} + z ^{2}})

\frac{( - x ^{2} + y ^{2} + z ^{2} ) y}{( x ^{2} + y ^{2} + z ^{2} ) ^{2}}

Solution steps

\frac{d}{d x} (\frac{x y}{x ^{2} + y ^{2} + z ^{2}})

Take the constant out:

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

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

Apply the Quotient Rule:

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

= y \frac{\frac{d}{d x} ( x ) ( x ^{2} + y ^{2} + z ^{2} ) - \frac{d}{d x} ( x ^{2} + y ^{2} + z ^{2} ) x}{( x ^{2} + y ^{2} + z ^{2} ) ^{2}}

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

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

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

Simplify

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

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

f (x) = ln ((2 x - 5) (3 x^{2} - 5))

\int cos^{3} (6 x) sin^{2} (6 x) d x

\int \frac{3 e ^{2 x}}{e ^{2 x} + 11 e ^{x} + 28} d x

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

8 sin (4 t) - 5 cos (4 t)
