derivative of

c y^{- 7}

- \frac{7 c}{y ^{8}}

Solution steps

\frac{d}{d y} (c y^{- 7})

Take the constant out:

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

= c \frac{d}{d y} (y^{- 7})

Apply the Power Rule:

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

= c (- 7 y^{- 7 - 1})

Simplify

c (- 7 y^{- 7 - 1}) : - \frac{7 c}{y ^{8}}

= - \frac{7 c}{y ^{8}}

\int 3 e^{\frac{x}{3}} d x

\int \frac{1}{2 x + 1} + \frac{1}{1 - x} d x

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

\int sin^{3} (4 x) cos^{3} (4 x) d x

y^{^{'}} = (2 x + y)^{2}
