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

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

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

Solution steps

\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))

f (x) = \frac{4 x}{x ^{2} + 1}

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

x \to 0 lim (\frac{5}{x ^{2} + x} - \frac{5}{x})

\frac{1}{2 - x}, 0

\frac{d}{d x} (\frac{4 x ^{2}}{x ^{2} - 1})
