Homework Statement
again there is no answer provided in the book!
a +bt +ct^2 = z where t is a real parameter, and a, b, c are complex numbers with b/c real
Homework Equations
The Attempt at a Solution
b/c real indicates that b and c are pure imaginary so when you split the equation into real and imaginary parts:
x = Re(a)
y = Im(a) + Im(b)t + Im(c)t^2
since t is a parameter, in the complex plane, the locus of z is a straight vertical line with x = Re(a)?
