Question

Complex

Answer 1

Let z on the circle |z| = 2
Estimate the value of |(z)/(z^3 - z^2 - 2z + 2)|

Answer 2

Firstly, factor the denominator

Answer 3

(z^2-2)(z-1)

Answer 4

(z - 1)(z + sqrt(2))(z - sqrt(2))

Answer 5

do we need partial fractions?

Answer 6

lolz sorry i don't know how to do this :'(

Answer 7

should we let z be a+bi lol

Answer 8

Answer 9

np, let's figure it out together

Answer 10

@Callisto

Answer 11

the result of partial fractions\[\frac{z+2}{z^2-2} - \frac{1}{z - 1}\]

Answer 12

i would just substitute z=2 inside it lolololol

Answer 13

you could find the remainder of function in z=1 z=+- root(2)
