Shifted ellipse

If the standard ellipse is shifted to have center (x ∘, y ∘) {\displaystyle \left(x_{\circ },\,y_{\circ }\right)}, its equation is (x − x ∘) 2 a 2 + (y − y ∘) 2 b 2 = 1. {\displaystyle {\frac {\left(x-x_{\circ }\right)^{2}}{a^{2}}}+{\frac {\left(y-y_{\circ }\right)^{2}}{b^{2}}}=1\.}

The axes are still parallel to the x - and y -axes.
