Show that the limit of the function:
f(z) = ( z / z-negated)^2
(z-negated -> by this i mean z with a bar above it)
as z tends to 0 does not exist. Do this be letting nonzero points z = (x,0) and z = (x,x) approach the origin.
note: it's not sufficient to simply consider points z = (x,0) and z = (0,y)© BrainMass Inc. brainmass.com October 10, 2019, 4:29 am ad1c9bdddf
The solution provides examples how to demonstrate the absence of limits for z/z-negated.
