shut marlin

a bit lost

#

were did the x and the y come from

#

and why did the 2 turn into a 4

#

the coefficient of the RHS

#

i dont even understand what it means by 'as z varies'

#

what does z represent

#

isnt it just the origin

#

You should watch some tl maths

#

odd scarab and why did the 2 turn into a 4

sqaured the whole thing

shut marlin Apr 3, 2024, 5:27 PM

#

odd scarab were did the x and the y come from

z=x+iy

#

odd scarab were did the x and the y come from

he basically converted the z thingies into cartesian form

#

shut marlin sqaured the whole thing

oh ok i see

#

so your saying each side individually makes a loci of a circle

#

basically

#

but why even square root to begin with?

#

odd scarab but why even square root to begin with?

thats the cartesian form

#

|Z| is tryna find the distance

odd scarab Apr 3, 2024, 5:30 PM

#

oh of course

#

its pythag

shut marlin Apr 3, 2024, 5:30 PM

#

formula for distance is rt(x^2+y^2)

#

ye

odd scarab Apr 3, 2024, 5:30 PM

#

yes

#

hm ok i think it makes sense
