1.

The polar of (2,3) with respect to the circle x^2+y^2-4x-6y+2=0 is?​

Answer»

Step-by-step explanation:

The POLAR of the general equation of CIRCLE w.r.t point (x

1

,y

1

) is

xx

1

+YY

1

+G(x+x

1

)+f(y+y

1

)+c=0

Then, the polar of the general equation of given circle w.r.t point (−2,3) is

⇒x(−2)+y(3)−2(x−2)−3(y+3)+5=0

⇒−4x+0+4−9+5=0

Equation of polar is x=0
