Eval

-- Special symbol: eval As an argument in a call to ev (<expr>), eval causes an extra evaluation of <expr>. See ev.

Example:

f:diff((y-((1/k)-(a*b^x)/k))^2,k);
g:eval(solve(f,k));
k:-((a*b^x)-1/y);
f:diff((y-((1/k)-(a*b^x)/k))^2,a);

          (%i1) [a:b,b:c,c:d,d:e];
          (%o1)                            [b, c, d, e]
          (%i2) a;
          (%o2)                                  b
          (%i3) ev(a);
          (%o3)                                  c
          (%i4) ev(a),eval;
          (%o4)                                  e
          (%i5) a,eval,eval;
          (%o5)                                  e

There are also some inexact matches for eval. Try ?? eval to see them.

(%o1)                                true
(%i2)
