(d^2)/(dx^2)((6pi^2)/(6-x))

解答

\frac{d ^{2}}{d x ^{2}} (\frac{6 π ^{2}}{6 - x})

\frac{12 π ^{2}}{( 6 - x ) ^{3}}

求解步骤

\frac{d ^{2}}{d x ^{2}} (\frac{6 π ^{2}}{6 - x})

\frac{d}{d x} (\frac{6 π ^{2}}{6 - x}) = \frac{6 π ^{2}}{( 6 - x ) ^{2}}

= \frac{d}{d x} (\frac{6 π ^{2}}{( 6 - x ) ^{2}})

\frac{d}{d x} (\frac{6 π ^{2}}{( 6 - x ) ^{2}}) = \frac{12 π ^{2}}{( 6 - x ) ^{3}}

= \frac{12 π ^{2}}{( 6 - x ) ^{3}}

n = 5 \sum \infty \frac{8 ^{n}}{9 ^{n}}

\int \frac{3}{5} - \frac{4}{x} d x

n = 1 \sum \infty n (sin (\frac{1}{n}))

\int (4 t^{2} - 3)^{2} d t
