                 (TAG3P) (Hoai and McKay 2001) is a grammar guided
                 genetic programming system that uses context-free
                 grammars along with tree-adjunct grammars as means to
                 set language bias for the genetic programming system.
                 In this paper, we show the result of TAG3P on the
                 problem of discovering trigonometric identities, one of
                 the benchmark problems in genetic programming (Koza
                 1992). The results show that although TAG3P did
                 successfully discover all three popular trigonometric
                 identities of the trigonometric function cos(2x),
                 namely, sin(2x+p /2), sin(p /2 -2x) and 1-2sin 2 (x),
                 it had a tendency to converge towards the first two
