Question

If a complex number z=x+iy then in terms of conjugate coordinates x can be written as :

Answer 1

@hartnn

Answer 2

the question is 'x can be.....' or 'z can be....' ?

Answer 3

x can be

Answer 4

then i need options...

Answer 5

z-zbar,z+zbar/2,none of the above

Answer 6

ohh....so find z bar first, what u get ?

Answer 7

How do i do that is it underroot(x^2+y^2)

Answer 8

ok, if z = a+bi
x bar = conjugate = a-bi
got this ?

Answer 9

*z bar

Answer 10

Ok

Answer 11

now what is z bar here ?

Answer 12

zbar=(x-yi)

Answer 13

now to eliminate y here, we add z and z bar
what u get ?

Answer 14

z+zbar=(x+yi)+(x-yi)=2x

Answer 15

so whats x ?

Answer 16

z+zbar/2 .Right Thanks :)

Answer 17

welcome ^_^
