the first one i took the circle x^2+y^2=1 which is written in z plane as : | z | = 1
and transformed it using w function i used the notation f(z) or Z







ااذا اخذنا حالة عامة r
u is between -r -1/r and r + 1/r
v is between -(r - 1/r) and r -1/r
و اظن ان المجال في w هو اقطعتين من المحورين حيث اكبر دائرة :
r---> infinity
تعطي المحورين
