need some math help here.

hi,

how do you express (x+6)/x in complex form, that is, (a +/- bi) form?

thanks

 

[Howard]

x+6/x is a real expression, isn't it?

 

[Corsairpro]

(x+6)/x is real for all x except when x = 0

yes it is.

i was asked this question by a friend.

how do you get the imaginary part when you're only given the real part?

confused me.

Doesnt it simplify to 1 + 6/x

 

[Yossarian]

I don't understand, if it's a real expression the "b" part is zero.

well you can do that only if you say x != 0

 

[Quixfire]

eakers would know.

Thats holds true for your original equation also, if you didn't notice. (0+6) / 0 is undefined as is 1 + 6/0. Which is why I felt saying x!=0 wasnt really necessary.
