Function: rhs (<expr>) Returns the right-hand side (that is, the second argument) of the expression <expr>, when the operator of <expr> is one of the relational operators < <= = # equal notequal >= >, one of the assignment operators := ::= : ::, or a user-defined binary infix operator, as declared by infix.

I(i):=-i/(s*R*C);
eq1: Vhp=Vin+Vlp-d*(tilt*Vbp1-0.5*Vbp2+(1/tilt)*Vbp3);
eq2: Vbp1=I(Vhp);
eq3: Vbp2=I(Vbp1);
eq4: Vbp3=I(Vbp2);
eq5: Vlp=I(Vbp3);
eq6: linsolve([eq1,eq2,eq3,eq4,eq5],[Vhp,Vbp1,Vbp2,Vbp3,Vlp]);
eq7: (eq6),s=%i*2*%pi*f,R=100000,C=100e-12,d=1,Vin=1.0,tilt=0.667;
db(v):=20*log(abs(v))/log(10);
plot2d([db(rhs(eq7[1])),db(rhs(eq7[2])),db(rhs(eq7[3])),db(rhs(eq7[4])),db(rhs(eq7[5]))],[f,8000,80000],[logx]);

When <expr> is an atom or its operator is something other than the ones listed above, rhs returns 0.

See also lhs.

Examples:

          (%i1) e: aa + bb = cc;
          (%o1)                     bb + aa = cc

          (%i4) [rhs (aa < bb), rhs (aa <= bb), rhs (aa >= bb),
                 rhs (aa > bb)];
          (%o4)                   [bb, bb, bb, bb]
          (%i5) [rhs (aa = bb), rhs (aa # bb), rhs (equal (aa, bb)),
                 rhs (notequal (aa, bb))];

          (%i6) e1: (foo(x) := 2*x);
          (%o6)                     foo(x) := 2 x
          (%i7) e2: (bar(y) ::= 3*y);
          (%o7)                    bar(y) ::= 3 y

          (%o8)                         x : y
          (%i9) e4: (x :: y);
          (%o9)                        x :: y
          (%i10) [rhs (e1), rhs (e2), rhs (e3), rhs (e4)];
