The value of sqrt(p^(-1)q).sqt(q^(-1)r).sqrt(r^(-1) p) is

(1)/(1+p+q^(-1))+(1)/(1+q+r^(-1))+(1)/(1+r+p^(-1))=1, if pqr=1

tan ^ (- 1) ((1) / (p + q)) + tan ^ (- 1) ((a) / (p ^ (2) + q + 1)) = cos ^ (- 1) p

If pqr = 1, then what is value of the expression (1)/(1+p+q^(-1)) +(1)/(1+q+r^(-1)) +(1)/(1+r+p^(-1)) ?
