Number of solutions of the equation cos ec theta=k in[0,pi] where k=lim_(n rarr oo)pi_(r=2)^(n)((r^(3)-1)/(r^(3)+1)) is

lim_ (x rarr1) (1-x ^ (2)) / (sin pi x)

lim_ (x rarr1) (cos pi (x) / (2)) / (1-sqrt (x))

lim_ (x rarr1) (2-x) ^ (tan ((pi) / (2) * x))

lim_ (x rarr1) (2-x) ^ (tan pi (x) / (2))
