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

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

Solution steps

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

Take the constant out:

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

= \frac{1}{3} \frac{d}{d x} (\frac{1 + 3 x}{x} (3 - x))

Apply the Product Rule:

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

f = \frac{1 + 3 x}{x}, g = 3 - x

= \frac{1}{3} (\frac{d}{d x} (\frac{1 + 3 x}{x}) (3 - x) + \frac{d}{d x} (3 - x) \frac{1 + 3 x}{x})

\frac{d}{d x} (\frac{1 + 3 x}{x}) = - \frac{1}{x ^{2}}

\frac{d}{d x} (3 - x) = - 1

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

Simplify

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

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

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

\int \frac{5 x}{x ^{2} - 1} d x

y^{^{''}} - 8 y^{^{'}} + 16 y = 0, y (0) = 5, y^{^{'}} (0) = 0
