anything else is given ?? say P have co-ordinates (x,y). Then you may take, A or B as origin, and apply distance formula to get PA and PB....

2. aceace Group Title

That is all that is given

3. aceace Group Title

so how would you do this... im still not so sure

4. manishsatywali Group Title

hartnn mean that take P(x,y) n i think u r provided wid coordinates of A and B apply distance formula to get equation of locus of the point P

5. aceace Group Title

ok thanks

you know distance formula, right ? Distance between points (x1,y1) and (x2,y2) is $$\huge d=\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}$$

fr ur info differnce of distance between twp points is an hyperbola m i ryt hartnn?
