\frac{d}{d x} (\frac{a ^{2} x}{( x + b ) ^{2}})

\frac{a ^{2} ( b - x )}{( x + b ) ^{3}}

Solution steps

\frac{d}{d x} (\frac{a ^{2} x}{( x + b ) ^{2}})

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

= \frac{a ^{2} ( b - x )}{( x + b ) ^{3}}

\int (6 x^{3}) d x

f (x) = \frac{cos ( x )}{cos ( x ) + 1}

y = \frac{6 x}{x ^{2} + 1}

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