pi:
Okay, I think I'll just stay safe with , just in case I forget to define it (then I might be screwed).

Thanks Mao!

pi:
noob question alert!

Could someone please show me how to find the and intercepts of ?

I can't seem to get a Cartesian equation out of it either (and MQ have no such problems/examples). I can do basic ones like:


, etc (solve for y and then find intercepts -although none in this case)

But am having trouble with finding Cartesian equations and intercepts of rays with translations.

Thanks  :D

Bonifacio:
Wouldn't z=x+yi

Therefore tan 2pi/3 = y+3/x-2 then solve from there?


tan 2pi/3 = -√3

-√3 (x-2) -3 =y then make x and y zero when necessary to find intercepts?

Greatness:
Perhaps you could sub in z= x +iy into the equatoin? And they could be translations??

Ahhh, I think that makes sense! Can anyone else concur?
