    I have tried pretty much everything I can think, tried making them equal each other with one squared or both squared etc and what always happens is that i have it finally simplified but than the cosh(x)s or cosh(y)s cancel out so I get no answer. Maybe I am not seeing something..

    Multiply the second equation by 2 and equate both equations. Turn the equations in terms of natural logs and solve.

    solve the second equation for sinhx

    square them

    X= log(3-root6). Y=log(-(root6-3)(5+2)root6))


    X= log(3+root6). Y=log(-(3+root6)(2root6-5))

    FP3 is such a pain in the ass, only thing I have to learn from is the edexcel book pretty much. Anyone who gets 100 UMS in that module.. hats off to them. Wish I had a had a brain like yours... , would just whizz through all of FP3 in no time .

    I can assure you it feels easy now but it did not feel easy when I was a student.

    The comments you hear from some people here such as "... I did FP3 in 2 days and got full UMS ..." are cringe-worthy.

    Just keep working.
