Быстрый ответ

z1 = -I*asinh(2)

$$z_{1} = - i \operatorname{asinh}{\left(2 \right)}$$

z2 = pi + I*asinh(2)

$$z_{2} = \pi + i \operatorname{asinh}{\left(2 \right)}$$

Сумма и произведение корней

сумма

-I*asinh(2) + pi + I*asinh(2)

$$- i \operatorname{asinh}{\left(2 \right)} + \left(\pi + i \operatorname{asinh}{\left(2 \right)}\right)$$

=

pi

$$\pi$$

произведение

-I*asinh(2)*(pi + I*asinh(2))

$$- i \operatorname{asinh}{\left(2 \right)} \left(\pi + i \operatorname{asinh}{\left(2 \right)}\right)$$

=

(-pi*I + asinh(2))*asinh(2)

$$\left(\operatorname{asinh}{\left(2 \right)} - i \pi\right) \operatorname{asinh}{\left(2 \right)}$$
