Ok I was finally able to draw this cursed parabola. May it go to hell. thank you again for your help! This page helped me a lot : https://en.wikipedia.org/wiki/Rotation_of_axesIn polar coordinates, (1, 3/2) is ##(\sqrt{13}/2, \theta)## where ##\theta = \arctan(1.5) \approx .98## (radians). If you rotate this by ##\pi/4## you get ##(\sqrt{13}/2, \theta + \pi/4)##, again in polar form. Can you work that out?
