Singular Manual: derivationPrint

| #### D.15.2.35 derivationPrint Procedure from library `difform.lib` (see difform_lib). Usage: phi; phi derivation Side effects: prints the given derivation Remarks: Prints the string returned by derivationToString with a ls-ordering on the generators Example:
    LIB "difform.lib";
    ring R = 0,(a,b,c,x,y,z),lp;
    diffAlgebra();
    ==> // The differential algebra Omega_R was constructed and the differential \
       forms dDa, dDb, dDc, dDx, dDy, dDz, da, db, dc, dx, dy, dz are available.
    /////////////////
    // Derivations //
    /////////////////
    list L; L[1] = list(dx,dy,dz,da,db,dc); L[2] = list(1,12x-y,z4aby, 2*b5x,0,xyz-abc);
    derivation phi = L;
    derivation phi_poly = 3ab - c2*x + z;
