derivative of

f (x) = 21 x^{3} ln (x)

21 (3 x^{2} ln (x) + x^{2})

Solution steps

\frac{d}{d x} (21 x^{3} ln (x))

Take the constant out:

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

= 21 \frac{d}{d x} (x^{3} ln (x))

Apply the Product Rule:

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

f = x^{3}, g = ln (x)

= 21 (\frac{d}{d x} (x^{3}) ln (x) + \frac{d}{d x} (ln (x)) x^{3})

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

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

= 21 (3 x^{2} ln (x) + \frac{1}{x} x^{3})

\frac{1}{x} x^{3} = x^{2}

= 21 (3 x^{2} ln (x) + x^{2})

\int \frac{2 x ^{4} + 2 5 x}{x} d x

y^{^{''}} + 6 y^{^{'}} + 9 y = 3 t + 5

\int (4 x^{3} - 3 x^{2} + 5) d x

\frac{d y}{d x} = \frac{x + y ^{2}}{2 y}

y = 2 x^{3} - 8 x
