Question

Find the equation of the circle passing through (0,0) and making intersect

Answer 1

Find the equation of the circle passing through (0,0) and making intercepts a and b on the coordinate axes.

Let the equation of the required circle be (x – h)2 + (y – k)2 = r2.

The equation of the circle now becomes (x – h)2 + (y – k)2 = h2 + k2.
