I'm just trying to see how it works. I'm new here and haven't been on a thread for a while now. And I'm really glad to be here. I absolutely love maths and I'm starting to learn how to program in C++ as well. Looking forward to be here and work with you guys!

Let P represent the complex number z, Q represent the complex number z + 1/z. Show that if P moves on the circle then |z| = 2, Q moves on the ellipse then,
x^2/25 + y^2/9 = 1/4

If z = 2cos(θ) + 2sin(θ)i, z + 1/z = (5/2)cos(θ) + (3/2)sin(θ)i.
Hence Q is on the ellipse with equation x²/25 + y²/9 = 1/4.
