Question

From a point on circle x^2+y^2+2gx+2fy+c=0 to tangents are drawn to circle x^2+y^2+2gx+2fy+csin^2alpha+(g^2+f^2)cos^2alpha=0 find angle

Answer 1

Answer:

If from any point P on the circle x^2+y^2 +2gx+2fy+c=0, tangents are drawn to the circle x^2 +y^2+2gx+2fy+csin^2alpha+(g^2+f^2)cos^2alpha= 0 , then find the angle between the tangents.
