RTP: x^2+y^2+z^2+2xyz=1

given that: arccos(x) + arccos(y) + arccos(z) =pi

I have gotten expressions for xyz from taking the cosine and sine of the given statement (bottom one), i keep getting a bunch of sqrt(1-x^2) and such for each variable and I cant seem to rearrange to get the top expression.
