derivative of

12 (x - \frac{1}{x})^{4}

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

Solution steps

\frac{d}{d x} (12 (x - \frac{1}{x})^{4})

Take the constant out:

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

= 12 \frac{d}{d x} ((x - \frac{1}{x})^{4})

Apply the chain rule:

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

= 4 (x - \frac{1}{x})^{3} \frac{d}{d x} (x - \frac{1}{x})

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

= 12 \cdot 4 (x - \frac{1}{x})^{3} (1 + \frac{1}{x ^{2}})

Simplify

= 48 (x - \frac{1}{x})^{3} (1 + \frac{1}{x ^{2}})

\int \frac{( 37 x + 5 )}{( 6 x + 1 ) ( x - 1 )} d x

\int (1 + 4 x^{2})^{\frac{1}{2}} d x

2 (ln (y)) y^{^{'}} - x^{3} y = 0

\int (- 3) d x

\int e^{s i n (θ)} d θ
