1Problem 3:Find the equation of the circle passingthrough the origin and intersecting the x-axis at a and they-axis at b(a≠0,b≠0).Problem 3:Find the equation of the circle passing through the origin and intersecting the x-axis at a and the y-axis at b( a≠0,b≠0). ...
【解析】Solution: x2+y2-ax -by=0.Since the circle passes the origin, we let the equa-ton be x2+y2+Dx+Ey=0.We know that the circle passes points(a, 0),(0,b)So a2+Da=0 and b^2+Eb=0Since a≠q0 , b≠q0 ,So D=-a,E=-b.The equation of the circle is x2+ y2-ax...
