r^2 cos^2 x = r sin x

y^2 = x

bear in mind: y = r*sen(theta) and x = r*cos(theta) interior the replace of coordinates. i will write t for theta (shorter). So; r = 2*sin(t) *** multiply the two components by utilizing r r^2=2*r*sin(t) *** bear in mind a million = cos^2(t)+sin^2(t) r^2*(cos^2(t)+sin^2(t))=2*r*sin(t) *** replace coordinates x^2+y^2=2y *** upload a million to the two components x^2+y^2-2y+a million=a million X^2+(y-a million)^2=a million *** completed Cheers
