derivative of

f (x) = \frac{x + x ^{3}}{x}

\frac{1 + 5 x ^{2}}{2 x}

Solution steps

\frac{d}{d x} (\frac{x + x ^{3}}{x})

Simplify

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

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

Apply the Product Rule:

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

f = x, g = 1 + x^{2}

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

\frac{d}{d x} (x) = \frac{1}{2 x}

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

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

Simplify

\frac{1}{2 x} (1 + x^{2}) + 2 x x : \frac{1 + 5 x ^{2}}{2 x}

= \frac{1 + 5 x ^{2}}{2 x}

y^{^{''}} - 7 y^{^{'}} + 12 y = 0, y (0) = 1, y^{^{'}} (0) = - 2

x \to 4 lim (\frac{5}{x - 3})

y = \frac{x - 2}{x - 2}

\frac{\partial}{\partial x} (2 e^{5 x y})

\int tan (8 x) d x
