Online published on 12 June, 2018. Abstract Let R be a non commutative 2, 3-torsion free prime ring and I be a non zero ideal of R. Let Dd(.,.):R×R → R be a symmetric left bi-derivation such that D(I,I) ⊏ I and d is a trace of D. If (i)[d(x),x]= 0, for all x,ε I (ii) [d(x),x] ε Z(Rx), for all xε I then D =0. Suppose that there exists symmetric left bi-derivations D1d(.,.)R×R → R and D2d(.,.)R×R → R and Bd(.,.)R×R → R is a symmetric bi-additive mapping, such that (i) D1 (d2;d(x),x) =0, for all x ε I (ii) d1 (d2;d(x),) = f(x), for all x ε I, where d1 and d2 are the traces of D1 and D2 respectively and f is trace of B, then either D1=0 or D2=0. If D acts as a left (resp. right) R -homomorphism on I, then D =0.
