Detailed Solution
Download Solution PDFसंकल्पना:
माना कि z = x + iy एक सम्मिश्र संख्या है।
- z का मापांक =
- arg (z) = arg (x + iy) =
- z का संयुग्म = x - iy
गणना:
माना कि z = x + iy है।
प्रश्नानुसार
arg(z) =
⇒
⇒
⇒ y =
साथ ही दिया गया है xy = 3
⇒ y =
y के मानों की तुलना करने पर, हमें निम्न प्राप्त होता है
⇒
⇒ x2 = 3
⇒ x = ±
∴ x =
साथ ही y =
सम्मिश्र संख्या z = x + iy =
z का संयुग्म = (z̅) =
