3) if we mix two solutions in unknown amounts to get a known total of known concentration, we set up simultaneous equations: one of the total amount, and one for the amount of solute Intro to Sets and Venn Diagrams 1) Venn diagrams can be helpful in problems with two overlapping sets ...
Word problems requiring exponential time The equivalence problem for Kleene's regular expressions has several effective solutions, all of which are computationally inefficient. In [1], we showed that this inefficiency is an inherent property of the problem by showing that the p... L.J. Stockmeyer...
