Termination Proof Script

Consider the TRS R consisting of the rewrite rules
1:    terms(N)  → cons(recip(sqr(N)))
2:    sqr(0)  → 0
3:    sqr(s)  → s
4:    dbl(0)  → 0
5:    dbl(s)  → s
6:    add(0,X)  → X
7:    add(s,Y)  → s
8:    first(0,X)  → nil
9:    first(s,cons(Y))  → cons(Y)
There is one dependency pair:
10:    TERMS(N)  → SQR(N)
The approximated dependency graph contains no SCCs and hence the TRS is trivially terminating.
