(d^2)/(dx^2)((x+1)e^x)

解答

\frac{d ^{2}}{d x ^{2}} ((x + 1) e^{x})

e^{x} x + 3 e^{x}

求解步骤

\frac{d ^{2}}{d x ^{2}} ((x + 1) e^{x})

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

= \frac{d}{d x} (e^{x} x + 2 e^{x})

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

= e^{x} x + 3 e^{x}

n = 1 \sum \infty sin (πn)

\frac{d}{d z} (\frac{i}{2 i} ln (\frac{i + i z}{i - i z}))

\frac{d}{d x} (csc^{4} (tan (e^{2 x})))

d er i v a t i v e y = 2 x^{3} + 3 x^{2} - 12 x + 1

\frac{\partial}{\partial x} (ln (3 x - 2 y))
