(Is this a homework problem?)
No. I still try solve the same problem ( polynomial equations )
Now I know how to do it.
I have system of 2 equations:
z=z4+2*c*z2+c2+c
abs(4*z3+4*c*z)=1
I want to solve it for c.
Result is a closed curve
I can solve :
z=z4+2*c*z2+c2+c
4*z3+4*c*z)=%e^(%i*t)
for various t from o to 2*pi
and I will have set of point which create the curve I need.
How to solve it ?
