Homework Statement
I have the expression ##a_2\overline{β} + a_3β## involving complex variables, where ##|β|≤1##. I was wondering, is it possible to determine for what ##a_2## and ##a_3## the expression is always real, for every ##β## satisfying ##|β|≤1##; or is there insufficient information?
Homework Equations
The Attempt at a Solution
I was under the impression an inquiry constituted an attempt. At any rate, I am not asking anyone to solve the problem; I am merely asking if solving such a problem is possible given the information. This doesn't come from a textbook, although I am sure it is considered a standard, textbook question.
How is this for an attempt?
##a_2 \overline{\beta} + a_3 \beta = r##, where ##r## is some real number.
##a_2 = \frac{r - a_3 \beta}{\overline{\beta}} = e^{i \theta} - a_3 e^{2 i \theta}##
