Быстрый ответ

z1 = I*asinh(3)

$$z_{1} = i \operatorname{asinh}{\left(3 \right)}$$

z2 = pi - I*asinh(3)

$$z_{2} = \pi - i \operatorname{asinh}{\left(3 \right)}$$

Сумма и произведение корней

сумма

0 + I*asinh(3) + pi - I*asinh(3)

$$\left(\pi - i \operatorname{asinh}{\left(3 \right)}\right) + \left(0 + i \operatorname{asinh}{\left(3 \right)}\right)$$

=

pi

$$\pi$$

произведение

1*I*asinh(3)*(pi - I*asinh(3))

$$1 i \operatorname{asinh}{\left(3 \right)} \left(\pi - i \operatorname{asinh}{\left(3 \right)}\right)$$

=

(pi*I + asinh(3))*asinh(3)

$$\left(\operatorname{asinh}{\left(3 \right)} + i \pi\right) \operatorname{asinh}{\left(3 \right)}$$
