(d^2)/(dx^2)(sec^2(x))

解答

\frac{d ^{2}}{d x ^{2}} (sec^{2} (x))

- 4 sec^{2} (x) + 6 sec^{4} (x)

求解步骤

\frac{d ^{2}}{d x ^{2}} (sec^{2} (x))

\frac{d}{d x} (sec^{2} (x)) = 2 sec^{2} (x) tan (x)

= \frac{d}{d x} (2 sec^{2} (x) tan (x))

\frac{d}{d x} (2 sec^{2} (x) tan (x)) = - 4 sec^{2} (x) + 6 sec^{4} (x)

= - 4 sec^{2} (x) + 6 sec^{4} (x)

\frac{d}{d x} ((tan (x))^{t a n (x)})

\int \frac{1}{x ^{2} + 49} d x

\int (x^{2} + x)^{10} (2 x + 1) d x

a re a y = 3 x, x + y = 4, y = 1 y = 0

\frac{d}{d x} (2 x^{\frac{3}{2}} + 4 x^{\frac{5}{4}})
