Find an equation of the circle with endpoints of a diameter are
P(, ) and QP(, )
an equation of the circle is ; so, we need the coordinates of the center (,) and the radius
First find the coordinates of the center : (,)
=>
=>
so, C (,) is the center
now find the radius ( u can find its length by taking the distance between one endpoint and C )
take (,) and P(, )
=>
= >
= >
= >
hence the equation is :
