Let u and v denote the real and
imagnarycomponents of the function f defined by
theequations

verify that the
cauchy-riemannequations and are satiesfied at the origin. also show that nevertheless fails to exists. whythis happen when the
cauchy riemann equations are satiesfied at theorigin but nevrtheless fails to exists.

answer: c.  

step-by-step explanation:

mixtures containing substances that get attracted to magnet can be separated using a magnet. we can separate iron from a mixture of sand and iron, as only iron attracts to the magnet.
