Polar moment of inertia of an elliptical plate $A$ thin plate of constant density covers the region bounded by the ellipse $x^{2} / a^{2}+y^{2} / b^{2}=1, a>0, b>0,$ in the $x y$ -plane. Find the first

moment of the plate about the origin. (Hint: Use the transformation $x=a r \cos \theta, y=b r \sin \theta . )$

{'transcript': "this problem, it's required toe plate moment of inertia about XX for a circle with the radius equal toe toe either Think, Felice Plate, you cleared I x for a dentist equal to one. Then calculate I i y And I note we can start boy needing i x So I x equal toe integration from negative to which is the radius to two and integration from negative four minus x square to route four minus x square for Why square do you? Why the yucks? So we can simply fly or solve it as integration from negative tool to two over three record full minus X squared Well, 4 3/2 DX and this should be equal to four by and from cemetery We can conclude that why is equal to Y X, which is equal to four boy, then I know he's some off my eggs And why? Why? So it will be equal toe a boy. Thank you"}
