    m^2=(1/2)(s^2+t^2)-(1/4)u^2
    (1/4)u^2=(1/2)(s^2+t^2)-m^2
    u^2=4(1/2)(s^2+t^2)-m^2
    u^2=2(s^2+t^2)-m^2
    u=sqrt(2(s^2+t^2)-m^2)

    Ok. No more bouncing around. We are doing calculus. So, let's stick to one course at a time. I would like for us to go through an entire college algebra textbook in the future, if you so desire to continue this journey.
