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

- sinh (x)

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the common derivative:

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

= - sinh (x)

f (x) = \frac{9}{x ^{2}}, at x = a

n = 2 \sum \infty \frac{1}{n \cdot ( n + 1 )}

f (x) = x^{2} (x^{2} - 8)

(1 + y^{2}) (d x) = x d y

\frac{\partial}{\partial y} (e^{3 x} cos (8 y))
