\frac{d}{d x} (x^{3} ln (x^{4} + 1))

3 x^{2} ln (x^{4} + 1) + \frac{4 x ^{6}}{x ^{4} + 1}

Solution steps

\frac{d}{d x} (x^{3} ln (x^{4} + 1))

Apply the Product Rule:

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

f = x^{3}, g = ln (x^{4} + 1)

= \frac{d}{d x} (x^{3}) ln (x^{4} + 1) + \frac{d}{d x} (ln (x^{4} + 1)) x^{3}

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

\frac{d}{d x} (ln (x^{4} + 1)) = \frac{4 x ^{3}}{x ^{4} + 1}

= 3 x^{2} ln (x^{4} + 1) + \frac{4 x ^{3}}{x ^{4} + 1} x^{3}

\frac{4 x ^{3}}{x ^{4} + 1} x^{3} = \frac{4 x ^{6}}{x ^{4} + 1}

= 3 x^{2} ln (x^{4} + 1) + \frac{4 x ^{6}}{x ^{4} + 1}

\int_{2}^{x^{2}} cos (t^{2} + 1) d t

\frac{d}{d x} ((8 x - 1)^{2})

\int 7^{c o s (x)} sin (x) d x

y = x cos (x)

x = 63 - 7 y^{2}, x = 7 y^{2} - 63
