Solve expr, vars, integers solves diophantine equations over the integers. Rather than unhappily accept the results of photographic typesetting techniques, knuth invented his own digital typesetting solution, tex, which would eventually become the standard typesetting system for mathematical and academic content. Ndsolveeqns, u, x, xmin, xmax finds a numerical solution to the ordinary differential equations eqns for the function u with the independent variable x in the range xmin to xmax. Reals, vars, complexes solves for real values of variables, but function values are allowed to be complex. In 1977, famed computer scientist donald knuth decided he didnt like the typesetting of the second edition of the art of computer programming. Apr 24, 2018 and the mathoverflow post goes on to conjecture that the continued fraction expansions of are involved in the closedform expressions for the position of the clearly visible peaks around zero distance, with 1, 1.
