derivative of

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

\frac{14}{y ^{2}} + \frac{9}{y ^{4}} + 5

Solution steps

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

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

\frac{d}{d y} (\frac{1}{y ^{2}} - \frac{3}{y ^{4}}) = - \frac{2}{y ^{3}} + \frac{12}{y ^{5}}

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

= (- \frac{2}{y ^{3}} + \frac{12}{y ^{5}}) (y + 5 y^{3}) + (1 + 15 y^{2}) (\frac{1}{y ^{2}} - \frac{3}{y ^{4}})

Simplify

(- \frac{2}{y ^{3}} + \frac{12}{y ^{5}}) (y + 5 y^{3}) + (1 + 15 y^{2}) (\frac{1}{y ^{2}} - \frac{3}{y ^{4}}) : \frac{14}{y ^{2}} + \frac{9}{y ^{4}} + 5

= \frac{14}{y ^{2}} + \frac{9}{y ^{4}} + 5

x \to \infty lim (y)

\frac{\partial}{\partial x} (x \cdot e^{\frac{y}{x}})

\int \frac{y ^{2}}{x} d x

f (x) = x^{4} - 1 3^{2} + 36, at x = 3

x \to 1 lim (\frac{3 x - 2}{x + 2})
