#

sterile thicket z should be given in form x+yi btw

Yeah thats the issue, afaik this is correct but I dont know how to get it in x+yi

#

#

okay when you calculate arg

gentle pine Nov 13, 2024, 8:47 PM

#

#

I was thinking something along the lines of this

sterile thicket Nov 13, 2024, 8:47 PM

#

yea

#

y/x = tan pi/4 = 1

#

y/x = 1

#

you get a quadratic

#

or should do

gentle pine Nov 13, 2024, 8:47 PM

#

Hm

#

Ill give it a go

sterile thicket Nov 13, 2024, 8:48 PM

#

because the xsqr + 16 cancel out

#

when you divide

#

so its just

#

6x/x^2 - 8 = 1

#

6x= x^2 -8

#

x is lamda btw

gentle pine Nov 13, 2024, 8:49 PM

#

sterile thicket because the xsqr + 16 cancel out

Wtf why did I not think of this

sterile thicket Nov 13, 2024, 8:49 PM

#

i dont have a lambda in my keyboard lol

gentle pine Nov 13, 2024, 8:49 PM

#

I feel so silly bruh

#

I was fully expanding the numerator and denominator

sterile thicket Nov 13, 2024, 8:49 PM

#

all good

gentle pine Nov 13, 2024, 8:49 PM

#

I was wondering why i had x^4 on the bottom....

sterile thicket Nov 13, 2024, 8:49 PM

#

now you will remember it lol

gentle pine Nov 13, 2024, 8:49 PM

#

Thanks for the help
