  • What makes a linear system of equations unsolvable?
    Until now, I only wrote about non-contradicting equations Equations can be linear independent but contradicting, then the system is also unsolvable E g: $$ 2x + 3y = 5\\ 2x + 3y = 10 $$ The right sides are multiples by $2$ resp $\frac{1}{2}$, but the left sides are not - so they are linear independent
  • word usage - Insolvable, insoluble, and unsolvable - English Language . . .
    And in fact there's some justification for preferring unsolvable simply because insoluble has another well-known sense insoluble [of a substance] - that cannot be dissolved [often, in water] but since that sense can't possibly apply to problems, there can be no ambiguity here
  • How do we know that an integral is unsolvable?
    It seems that for the most part, the equations becomes "unsolvable" about halfway through the work, once you hit an impossible integral For example, in my textbook, they are showing how using the integrating factor technique can go wrong, and end up with this:
  • Does an unsolvable game exist? (And can you formulate an example?)
    In designing an unsolvable game, it seems like we need to find a game where a process or structure, perhaps a formal language of some kind, is continued as long as is possible For example, a game could be constructed in which both players place Wang tiles, and when it is no longer possible for a player to place a Wang tile, they loose
  • Unsolvable Differential Equation? - Mathematics Stack Exchange

  • abstract algebra - Is there a simple explanation why degree 5 . . .
    $\begingroup$ unsolvable by radicals (and arithmetic), you mean The short answer is something to the effect of studying the ways in which you can construct numbers as roots of polynomials, and how such constructions can be built from elementary, irreducible constructions
  • puzzle - Minimum Number of Clues for Unsolvable Sudoku - Mathematics . . .
    I am going to make a distinction between "unsolvable" and "invalid" Sudoku A Sudoku is unsolvable if there is no way to fill in all the spaces without violating one of the rules of Sudoku An Sudoku is invalid if the clues given violate one of the rules of Sudoku The minimum number of clues needed for a invalid Sudoku is obviously 2
  • How to determine if a linear system is solvable
    If the determinant of the left hand matrix is 0, then the system is dependent and has a free variable This means the system has an infinite number of solutions Finding if a system has no solutions is rather more complex
  • Do we expect that unsolvable differential equations would have an . . .
    Or is something like this fundamentally unsolvable for some reason? If it would be possible, are mathematicians working to discover these new mathematical terms? It fascinates me that we don't have the math to cleanly describe the three-body problem, for example, and it's hard to imagine that a clean solution wouldn't exist if we simply knew more
