ALLBRANCH _ _ _ _ _ _ _ _ _ _ _ _ switch

When allbranch is on, the operator solve selects all branches of solutions. When allbranch is off, it selects only the principal branches. Default is on.

examples:

solve(log(sin(x+3)),x); 

  {X=2*ARBINT(1)*PI - ASIN(1) - 3,
   X=2*ARBINT(1)*PI + ASIN(1) + PI - 3}


off allbranch; 

solve(log(sin(x+3)),x); 

  X=ASIN(1) - 3

arbint(1) indicates an arbitrary integer, which is giv en a unique identifier by REDUCE, showing that there are infinitely many solutions of this type. When allbranch is off, the single canonical solution is given.
