What is the max value?
The answer is
Check in image...
Put the coordinate
#color(red)((0,-2))#on the equation and you will get the value greater than #color(red)(0#. It means the point #color(red)(p(0,-2)#is outside the circle.
We determined the value of
#bar"PQ"#by distance formula.
Not for JEE level, but a huge calculation. Will try to solve it with shorter method.
For any problem about handwriting , notify me.
Hope it helps...
given a circle :
rewrite the equation :
Given the equation of the circle
The standard form of this equation :
So coordinates of its center is
So coordinates of any point
The coordinates of given point
