1.] the equation of a locus is x2+y2-4x+6y-3=0.Show that the equation becomes x2+y2=16 if the origin is shifted.
Dear Ashwathy x2+y2-4x+6y-3=0 (x-2)2 + (y+3)2 =16 this is a equation of circle having center ( 2,-3) so now shift the origin at (2,-3) x' =x+2 y'=y-3 so equation become x2+y2 =16 Please feel free to post as many doubts on our discussion forum as you can.If you find any question Difficult to understand - post it here and we will get you the answer and detailed solution very quickly.

Dear Ashwathy
x2+y2-4x+6y-3=0
(x-2)2 + (y+3)2 =16
this is a equation of circle having center ( 2,-3)
so now shift the origin at (2,-3)
x' =x+2
y'=y-3
so equation become x2+y2 =16
