Homework Statement
Hello! I have 2 bodies initially at rest, of equal masses with the distance between them a and coordinates ##(a cos(\theta),a sin(\theta))## and ##(-a cos(\theta),-a sin(\theta))##. If we denote ##a_x## and ##a_y## the horizontal and vertical distance between them they satisfy a relationship which gets reduced to what I write in 3. Show that they rotate around the origin (keeping the distance between them fixed)

The Attempt at a Solution
##\frac{d^2 a_x}{dt^2} = A(1+i)\omega^2e^{-i\omega t}## and ##\frac{d^2 a_y}{dt^2} = A(-1+i)\omega^2e^{-i\omega t}##. So I get ##a_x = A(1+i)e^{-i \omega t}+Bt+D## and ##a_y = A(-1+i)e^{-i \omega t}+Et+F##. If I put the condition to be stationary in the beginning (t=0), I get ##B=A(1+i)## and ##E=A(-1+i)## But I am kinda stuck. What should I do from here?
