\frac{d}{d x} (\frac{2 x ^{4}}{b ^{2} - x ^{2}})

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

Solution steps

\frac{d}{d x} (\frac{2 x ^{4}}{b ^{2} - x ^{2}})

Take the constant out:

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

= 2 \frac{d}{d x} (\frac{x ^{4}}{b ^{2} - x ^{2}})

Apply the Quotient Rule:

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

= 2 \cdot \frac{\frac{d}{d x} ( x ^{4} ) ( b ^{2} - x ^{2} ) - \frac{d}{d x} ( b ^{2} - x ^{2} ) x ^{4}}{( b ^{2} - x ^{2} ) ^{2}}

\frac{d}{d x} (x^{4}) = 4 x^{3}

\frac{d}{d x} (b^{2} - x^{2}) = - 2 x

= 2 \cdot \frac{4 x ^{3} ( b ^{2} - x ^{2} ) - ( - 2 x ) x ^{4}}{( b ^{2} - x ^{2} ) ^{2}}

Simplify

2 \cdot \frac{4 x ^{3} ( b ^{2} - x ^{2} ) - ( - 2 x ) x ^{4}}{( b ^{2} - x ^{2} ) ^{2}} : \frac{2 ( 4 b ^{2} x ^{3} - 2 x ^{5} )}{( b ^{2} - x ^{2} ) ^{2}}

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

\int (2 - 3 x)^{3} d x

\frac{d}{d x} (\frac{ln ^{2} ( x )}{x})

x^{2} - 3 x y = 10, (1, - 3)

y^{^{''}} - y = 5 sin (2 t y) (0)
