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

解

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

解

2 (- sec (x) + 2 sec^{3} (x))

解答ステップ

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

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

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

\frac{d}{d x} (2 sec (x) tan (x)) = 2 (- sec (x) + 2 sec^{3} (x))

= 2 (- sec (x) + 2 sec^{3} (x))
