Question

How do you convert `9=(x-4)^2+(y+12)^2` into polar form?

Answer 1

This looks like the equation for a circle

Explanation:

A circle of radius 3 and center located at x = 4 and y = -12 obeys the above equation, which you can write in Cartesian coordinates (x,y) or polar coordinates, r, theta. In which case you want to make a change of coordinates centered on the (4,-12) center of the circle in which case the equation is imply r = 3
