Input (TPDB TRS_Equational/Mixed_AC/differ)

The rewrite relation of the following equational TRS is considered.

dx(X) 1 (1)
dx(0) 0 (2)
dx(1) 0 (3)
dx(a) 0 (4)
dx(+(f,g)) +(dx(f),dx(g)) (5)
dx(*(f,g)) +(*(dx(f),g),*(dx(g),f)) (6)
dx(-(f,g)) -(dx(f),dx(g)) (7)
dx(neg(f)) neg(dx(f)) (8)
dx(/(f,g)) -(/(dx(f),g),/(*(dx(g),f),exp(g,2))) (9)
dx(ln(f)) /(dx(f),f) (10)
dx(exp(f,g)) +(*(dx(f),*(exp(f,-(g,1)),g)),*(dx(g),*(exp(f,g),ln(f)))) (11)
