sinh (x)

$$\sinh^{9}{\left (x \right )}$$

Первая производная

      8           
9*sinh (x)*cosh(x)

$$9 \sinh^{8}{\left (x \right )} \cosh{\left (x \right )}$$

Вторая производная

      7    /    2            2   \
9*sinh (x)*\sinh (x) + 8*cosh (x)/

$$9 \left(\sinh^{2}{\left (x \right )} + 8 \cosh^{2}{\left (x \right )}\right) \sinh^{7}{\left (x \right )}$$

Третья производная

      6    /       2             2   \        
9*sinh (x)*\25*sinh (x) + 56*cosh (x)/*cosh(x)

$$9 \left(25 \sinh^{2}{\left (x \right )} + 56 \cosh^{2}{\left (x \right )}\right) \sinh^{6}{\left (x \right )} \cosh{\left (x \right )}$$
