derivative of

y = \frac{3 x ^{5} + 9}{x ^{3}}

\frac{3 ( 2 x ^{5} - 9 )}{x ^{4}}

Solution steps

\frac{d}{d x} (\frac{3 x ^{5} + 9}{x ^{3}})

Apply the Quotient Rule:

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

= \frac{\frac{d}{d x} ( 3 x ^{5} + 9 ) x ^{3} - \frac{d}{d x} ( x ^{3} ) ( 3 x ^{5} + 9 )}{( x ^{3} ) ^{2}}

\frac{d}{d x} (3 x^{5} + 9) = 15 x^{4}

\frac{d}{d x} (x^{3}) = 3 x^{2}

= \frac{15 x ^{4} x ^{3} - 3 x ^{2} ( 3 x ^{5} + 9 )}{( x ^{3} ) ^{2}}

Simplify

\frac{15 x ^{4} x ^{3} - 3 x ^{2} ( 3 x ^{5} + 9 )}{( x ^{3} ) ^{2}} : \frac{3 ( 2 x ^{5} - 9 )}{x ^{4}}

= \frac{3 ( 2 x ^{5} - 9 )}{x ^{4}}

\frac{s ^{2} - 1}{( s - 2 ) ^{6}}

\frac{d y}{d x} + 20 y = sin (x)

\frac{d}{d x} (3 arctan (x))

\frac{d ^{3}}{d x ^{3}} ((x^{2} - 1)^{3})

\int_{0}^{\frac{π}{2}} 15 cos^{5} (x) d x
