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

2 cosh (x) sinh (x)

Solution steps

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

Apply the chain rule:

2 cosh (x) \frac{d}{d x} (cosh (x))

= 2 cosh (x) \frac{d}{d x} (cosh (x))

\frac{d}{d x} (cosh (x)) = sinh (x)

= 2 cosh (x) sinh (x)

\frac{d y}{d x} = 8 x^{3} e^{- 2 y}, y (1) = 0

\frac{d}{d x} (\frac{x ^{2} + 14}{x ^{8}})

y^{^{''}} + 4 y^{^{'}} + 6.25 y = 3.125 (x + 1)^{2}

y^{^{'}} = 2 x y^{- 2}

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