    Sorry, yes Pro, s should be 42.468476 but using that value still give d = 50.xxxxxx not the 1000 as expected?
    Many thanks

    Actually, checking back now, I think there is an error somewhere.

    I'll get back to it in a while

    Re: Practical problem

    OK, with no factoring done, here is the correct solution

    d=\dfrac{f(h+s)+\sqrt{f^2(h+s)^2-(2h+s)(sf^2-sh^2)}}{2h+s}

    All the best
