FNQ1nreturns the value of the Legendre function of the second kind, degree one, and ordernofx,Qn1(x).Nmust be positive or zero.
Errors
FNQ1ncauses an HTBasic error if its arguments are not of the types listed in the usage section, above, 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 ofQn1 using a recursion from the values ofQ11 andQ21. The computation time increases withn-1 and the computation accuracy decreases withn-1.
