FNQnreturns the value of the Legendre function of the second kind, degree zero, and ordernofx,Qn(x).Nmust be positive or zero.
Errors
FNQncauses an HTBasic error if its arguments are not of the types listed in the usage section, above, ifnis negative, or if the polynomial's absolute value would be larger than MAXREAL, the largest value representable.

Note
Forn> 2, the algorithm used computes the value ofQnusing a recursion from the values ofQ1 andQ2. The computation time increases withn-1 and the computation accuracy decreases withn-1.
