| I obtain something of this sort if I save a notebook as plain text. |
| Playing around with this problem I came up with a couple of variations: ContourPlot[{x + y == 1, x - y == 1}, {x, -2, 2}, {y, -2, 2}, Epilog -> Translate[Rotate[Line[1/5 {{1, 0}, {1, 1}, {0, 1}}], Pi/4, {0, 0}], ... |
| I opened the notebook in a text editor, and found the option `WindowSize->{Full, Full}` near the end. If I remove it, then the window size becomes normal. Anyway, on my mac I can resize it by dragging the pointer to the top of the screen, so that the... |
| You should define your list of matrices as `m=`, not as `m_List=`. Anyway, yours is a list of matrices, and `ResourceFunction["CofactorMatrix"]` works on matrices, not on lists of matrices. Your matrices all have two rows of zeros. No wonder that the... |
| It seems that `Filling` completely kills the `Exclusions`: pl = Plot[Ceiling[x], {x, -5, 5}, Filling -> Axis, ExclusionsStyle -> Red, Exclusions -> Range[-5, 5]] FreeQ[pl, Red] |
| I never use `$Assumptions`, so I am no expert. It surely looks like a bug, though. |
| I would express the Goldbach conjecture this way: Resolve@ForAll[n, {Element[n, Integers], n > 1}, Exists[{i, j}, Element[i | j, PositiveIntegers], 2 n == Prime[i] + Prime[j]]] |
| I am not aganst `Thread`: Thread[lhs -> rhs] |
| The indefinite integral has a branch cut discontinuity in your interval: Block[{a = 1.2 - 3.4 I, f = 5.6 - 7.8 I}, ReImPlot[ Log[(a + x)/(a - f)] Log[f + x] + PolyLog[2, -((f + x)/(a - f))], {x, 2, 2.5}]] That is why it... |
| This variant seems to work: DynamicModule[{f, x = 5, arg, val}, f[x_] := {x, Sqrt[x]}; Column[{Slider[Dynamic@x, {0, 25, 1}], Dynamic[{arg, val} = f[x]], Row[{"{arg,val} = ", Dynamic@{arg, val}}]}]] |
