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)

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

=

pi

$$\pi$$

произведение

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

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

=

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

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