| Jun 22, 2021 at 11:48 | comment | added | mathlove | If "$P$ (forming an angle of $\pi/4$ with the major axis)", then the coordinates of $P$ is $(2/\sqrt 5,2/\sqrt 5)$, not $(2\cos\frac{\pi}{4},\sin\frac{\pi}{4})$. If "$P$ whose eccentric angle is $45^\circ$", then the coordinates of $P$ is $(2\cos\frac{\pi}{4},\sin\frac{\pi}{4})$. | |
