(d^2)/(dx^2)(6sec(x))

\frac{d ^{2}}{d x ^{2}} (6 sec (x))

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

Solution steps

\frac{d ^{2}}{d x ^{2}} (6 sec (x))

\frac{d}{d x} (6 sec (x)) = 6 sec (x) tan (x)

= \frac{d}{d x} (6 sec (x) tan (x))

\frac{d}{d x} (6 sec (x) tan (x)) = 6 (- sec (x) + 2 sec^{3} (x))

= 6 (- sec (x) + 2 sec^{3} (x))

\int_{0}^{3 π} sin^{2} (x) d x

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

y^{^{''}} - 4 y^{^{'}} + 9 y = 0, y (0) = 0, y^{^{'}} (0) = - 8

f (x) = \frac{x ^{3}}{9}

\frac{d y}{d x} - 3 y = - 7 sin (x) - 7 cos (x)
