(d^2)/(dx^2)(5x^4-5x^2+7)

解答

\frac{d ^{2}}{d x ^{2}} (5 x^{4} - 5 x^{2} + 7)

60 x^{2} - 10

求解步骤

\frac{d ^{2}}{d x ^{2}} (5 x^{4} - 5 x^{2} + 7)

\frac{d}{d x} (5 x^{4} - 5 x^{2} + 7) = 20 x^{3} - 10 x

= \frac{d}{d x} (20 x^{3} - 10 x)

\frac{d}{d x} (20 x^{3} - 10 x) = 60 x^{2} - 10

= 60 x^{2} - 10

d er i v a t i v e y = 2 e^{x}

\int_{0}^{π} (9 e^{x} + 7 sin (x)) d x

\int x \cdot a^{x} d x

\int \frac{1}{4 - 49 x ^{2}} d x
