A point P (x,y) moves so that AP and BP are perpendicular, given A = (3,2) and B = (-4,1). Find the equation of the locus of P.

Yeah so, it was rather weird and I didn't even know how to start this one.

it's going to be a circle excluding the points a&b, ab is a diameter, and the midpoint of ab is the centre of the circle, radius is half times the diameter, so half times the distance ab.

i'd do all the equations for you but on my phone and it's not possible. hope that helps somehow!

let me know if you need any explanations =]].
