From there you should be able to finish.
The complex numbers Z and W are represented, respectively, by points P(x, y) and Q(u,v) in Argand diagrams and
By first writing Z+1=1/W
(a) Show that
and find an expression for y in terms of u and v.
(b) The point P moves along the circle (x+1)˛ + y˛ = 4. Find the equation of the locus Q.
Could somebody please show a step by step solution to this please? I really don't know how to answer these type of questions. Is there a general method?
I am awfully sorry that you did not find that rather straightforward answer did not help you.
Also, I hope that you are not expecting to be given a step-by-step, ready to hand in, solution.
If that is what you want then you are short selling yourself.
You should want to learn the concepts involved here.
You need to see that the real part of the left side must equal the real part of the right. Likewise the imaginary part of the left side must equal the imaginary part of the right side.
Look - if you want or need another view after a member has provided help then make another post SHOWING SOME KIND OF WORK. The more you seem actually interested in learning instead of having someone give you answers, the more you'll get help I'm sure.
