Pˇríklad: f (z) = z 2 . Uvažujme dvě kolmé pˇrímky<br />

p1 = {1 + jt | t ∈ R} , t = 1<br />

p2 = {s + j | s ∈ R} , s = 1<br />

f (p1) = {1 − t 2 + 2jt | t ∈ R} .<br />

f (p2) = {s 2 − 1 + 2js | s ∈ R} .<br />

vektory tečen jsou kolmé:<br />

(−2t, 2) tj. pro t = 1 (−2, 2)<br />

(2s, 2) tj. pro s = 1 (2, 2).<br />

Pro z = 0 je f ′ (z) = 0 a úhly se nezachovají.<br />
