(d^2)/(dx^2)(arccos(3x))

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

- \frac{27 x}{( 1 - 9 x ^{2} ) ^{\frac{3}{2}}}

Solution steps

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

\frac{d}{d x} (arccos (3 x)) = - \frac{3}{1 - 9 x ^{2}}

= \frac{d}{d x} (- \frac{3}{1 - 9 x ^{2}})

\frac{d}{d x} (- \frac{3}{1 - 9 x ^{2}}) = - \frac{27 x}{( 1 - 9 x ^{2} ) ^{\frac{3}{2}}}

= - \frac{27 x}{( 1 - 9 x ^{2} ) ^{\frac{3}{2}}}

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

\int \frac{x ^{2}}{x ^{2} - 25} d x

\int \frac{1 + y ^{2}}{y} d y

\frac{d}{d x} ((x^{3} - x + 1)^{10})

y = \frac{1}{x ^{4}}, (1, 1)
