    the hyperbola...

    Stuck on a question. Goes like this

    Points A(0,0) B(4,0) C(0,3) and P(x,y)

    Difference between PY and PA is 6.6

    Treating A and B as the foci of the hyperbola what is the equation?

    More specifically, the question asks to determine the values necessary to deduce the equation

    Thanks in advance

    Hello, delpin!

    If no one is responding, it's because we don't understand the problem.


    Points A(0,0) B(4,0) C(0,3) and P(x,y)

    Difference between PY and PA is 6.6 . Where is point Y ?

    Treating A and B as the foci of the hyperbola what is the equation?

    More specifically, the question asks to determine the values necessary to deduce the equation.

    If PB - PA = 6.6, there is enough information to determine the hyperbola.
    . . Then what is the purpose of point C?

    Apologies but PY should have read PB...

    Point C is probably to do with another part of the same question though we can work out the difference PC-PB=1.32
