Various factors affect the simplicity and readability of the result and also, in some cases, the speed at which it is reached:
- How clearly have you defined your problem? The fewer unknowns you use, the faster the calculation and the more likely that the resulting expression will be simple and clear.
- How constrained is the problem? Fully constrained problems produce better results than underconstrained ones, because you control which unknowns are used.
- Using intermediate variables makes expressions less likely to simplify, but more likely to produce a result.
- For faster calculations, use lower settings of Intermediate Value Complexity.
- Use assumptions for simpler results, if your expression has absolute values in it. But check the assumption to make sure it’s what you intend; if not, change the drawing to reflect your intention more accurately.
