derivative of

f (x) = 4 x^{- \frac{3}{8}}

- \frac{3}{2 x ^{\frac{11}{8}}}

Solution steps

\frac{d}{d x} (4 x^{- \frac{3}{8}})

Take the constant out:

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

= 4 \frac{d}{d x} (x^{- \frac{3}{8}})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= 4 (- \frac{3}{8} x^{- \frac{3}{8} - 1})

Simplify

4 (- \frac{3}{8} x^{- \frac{3}{8} - 1}) : - \frac{3}{2 x ^{\frac{11}{8}}}

= - \frac{3}{2 x ^{\frac{11}{8}}}

\frac{d}{d x} (\frac{x ^{7}}{7} - x^{3} - \frac{3}{x} + \frac{1}{5 x ^{5}})

x \to 0 lim (\frac{sin ( 3 x ^{2} )}{x})

\int sin (3 x) sin (x) d x

\int_{- 2}^{3} (4 x^{2} + 8) - (3 x + 2) d x

\int 7 x^{5} d x
