Z (1/3 + i/4) = Z "conjugada" + 1
***********************************
***********************************
Z=(a+bi)
Z "conjugada"=(a-bi)
con esto podemos resolver:
***********************************
***********************************
(a+bi)(1/3 + i/4) = (a-bi) + 1
a/3+ai/4 +bi/3+bi²/4 = a-bi+1
a/3+ai/4 +bi/3-b/4 = a-bi+1
(a/3-b/4) + (ai/4+bi/3) = (a+1) - (bi)
igualamos cada lado asi:
a/3-b/4 = a+1 ai/4+bi/3 = -bi
-1 = a-a/3+b/4 a/4+b/3 = -b
-1 = 2a/3+b/4 a/4+b/3+b = 0
2a/3+b/4 = -1 a/4+4b/3=0
(8a+3b)/12 = -1 (3a+16b)/12 = 0
8a+3b = -12........(1) 3a+16b = 0...........(2)
*********************************************************************
*********************************************************************
ahora resolvamos el sistema planteado asi:
8a+3b = -12........(1)
3a+16b = 0...........(2)
*********************************************************************
*********************************************************************
3(1) -8(2)
24a+9b = -36
-24a-128b = 0
---------------------
-119b = -36
b= -36/119
b=36/119
b reemplazo en (2)
3a+16b=0
3a+16(36/119)=0
3a+576/119=0
3a = -576/119
a = -576/357
a = -192/119
*********************************************************************
*********************************************************************
dados a y b respectivamente tenemos Z:
Z = (a+bi) = (-192/119+36/119i)
Z "conjugada"=(a-bi)=(-192/119-36/119i)
listo espero te sirva :)
