1. The problem statement, all variables and given/known data In the exercise, we solved the 2D Harmonic Oscillator in kartesian (x,y) and polar (r,φ) coordinates. We found out that both have the same energy levels, but they look very different, when I plot them. What am I missing? The polar solution seems more like it. 2. Relevant equations 3. The attempt at a solution Two examples: If needed, I can give you more details about the formulas or plots!
