Hi somebody,
If any of my complex number questions prove to be wrong (or you have reason to question my answers) can you please let me know. :)
Find all complex numbers z such that
|z - 3| = |z+i| = |z -3i|
letz=a+bi|(a−3)+bi|=|a+(b+1)i|=|a+(b−3)i|(a−3)2+b2=a2+(b+1)2=a2+(b−3)2a2−6a+9+b2=a2+b2+2b+1=a2+b2−6b+9−6a+9=2b+1=−6b+9 2b+1=−6b+98b=8b=1 −6a+9=3−6a=−6a=1
So I get
z=1+i
