derivative of

(\frac{1}{y ^{2}} - \frac{7}{y ^{4}}) (y + 5 y^{3})

\frac{34}{y ^{2}} + \frac{21}{y ^{4}} + 5

Solution steps

\frac{d}{d y} ((\frac{1}{y ^{2}} - \frac{7}{y ^{4}}) (y + 5 y^{3}))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = \frac{1}{y ^{2}} - \frac{7}{y ^{4}}, g = y + 5 y^{3}

= \frac{d}{d y} (\frac{1}{y ^{2}} - \frac{7}{y ^{4}}) (y + 5 y^{3}) + \frac{d}{d y} (y + 5 y^{3}) (\frac{1}{y ^{2}} - \frac{7}{y ^{4}})

\frac{d}{d y} (\frac{1}{y ^{2}} - \frac{7}{y ^{4}}) = - \frac{2}{y ^{3}} + \frac{28}{y ^{5}}

\frac{d}{d y} (y + 5 y^{3}) = 1 + 15 y^{2}

= (- \frac{2}{y ^{3}} + \frac{28}{y ^{5}}) (y + 5 y^{3}) + (1 + 15 y^{2}) (\frac{1}{y ^{2}} - \frac{7}{y ^{4}})

Simplify

(- \frac{2}{y ^{3}} + \frac{28}{y ^{5}}) (y + 5 y^{3}) + (1 + 15 y^{2}) (\frac{1}{y ^{2}} - \frac{7}{y ^{4}}) : \frac{34}{y ^{2}} + \frac{21}{y ^{4}} + 5

= \frac{34}{y ^{2}} + \frac{21}{y ^{4}} + 5

\frac{d}{d x} (\frac{1 - sin ( x )}{1 + cos ( 2 x )})

f (x) = - 1

\frac{d}{d z} (\frac{x}{y} - y z)

x \to 2 - lim (cos (\frac{1}{x - 2}))

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