| Yay! Now it all makes sense. I'm not very familiar with Wolfram|Alpha or Alpha Notebooks, so that's why I couldn't understand the problem before. |
| I'm sorry, but I've been poking through this for like an hour and I have no idea what your code is doing. Can you minimize this example? Or can you at least pinpoint where you're actually applying the "trapezoidal method" for an integral and what... |
| Sure! But it would really help to know what you want to do with these plot expressions in your function. Each plot function could have different options or different argument patterns, so if you're inspecting the expression inside your function, you... |
| As has been pointed out, the expected way to treat expressions as if all variables are real is to use `ComplexExpand`. And while I cannot read the mind of Wolfram developers, it seems to me that `Re` is not intended to deal with arbitrary expressions... |
| Once you have the structure, you can create whatever labels you want. In my example, the symbol `result` was assigned a value that was a list of all of the desired vectors. So, `result[[1]]` could be the label for the first vector, etc. That means... |
| Do you mean just the second elements instead of the last elements? GroupBy[{{a, 1, x}, {b, 2, v}, {a, 3, y}, {a, 7, z}, {b, 2, w}}, First -> (#[[2]] &), Total] (* 11, b -> 4|> *) |
| Do you want it in a format that other applications can use? Or do you only need to import back into Mathematica? Or do you just want to avoid re-generating the Dataset again (avoid being dependent on those original files)? |
| For a particular instance, you can use `HoldForm`: HoldForm[D[f[x, y], x]] For a "global" solution, you could probably use `Format` to define how you want `Derivative` to display in output cells (you could restrict it to `TraditionalForm`... |
| I'm sorry, but I've lost the plot. I don't understand where you're going with this. I don't understand why my answers are confusing, and so I don't know how to improve them. Have you been able to get something to actually work? Have you tried the... |
| Daniel Lichtblau already mentioned that! Thanks! Here's what you can do Sasha: altQuotientRemainder[m_Integer, n_Integer?Negative] := -QuotientRemainder[-m, n]; altQuotientRemainder[m_Integer, n_Integer] := QuotientRemainder[m, n] ... |
