Question

Sa se scrie afixul z, arg(z), Arg(z) si |z| pentru punctele din desen

Answer 1

F.

z= -2√2-2√2i

TgФ=(-2√2/-2√2=1

Esti in   cadranul   3 arg z=π/4+π=5π/4

_______-----------------------------------------------------------

B

z=3/2+3i/2

tgx=(3/2)/(3/2)=1=> x=π/4

argz=π/4

Argz=π/4+2kπ

lzl=(3/2)²+(3/2)²=9/4+9/4=9/2

Argz=5π/4+2kπ

lzl=(-2√2)²+(-2√2)²=8+8=16

Revin   imediat

H

z=3-3i

Tgx=(-3)/3=-1

Esti  in   cadranul  4

x=2π-π/4=7π/4

argz=7π/4

Argz=7π/4+2kπ

lzl=(3²+(-3)²=9+9=18
