| Yes, I was surprised too, but then realized that it was not too surprising. It's not too uncommon for kids to count things. They also like counting the tick marks when Axes->True. Some things should be simple enough for the youngest kids, as... |
| [MorphologicalGraph][1] is a useful function. An example with a maze in the documentation, then all you need is to identify the start and end points and FindShortestPath will give a solution. I am not an expert but I believe that the edge weights... |
| This is a nice discovery. It appears to be mostly class 3 but it has some localized structures like class 4. There is also irregular boundary behavior, some of which makes me think it has a large radius. It reminds me of some of the [3 color... |
| You are looking for something more like this model[{A_, II_, Y_, CC_}] := Module[{Anew, Knew, Rnew}, Anew = (1 + z) A; Rnew = a Anew CC; Knew = (1 - a) (Sqrt[b] Rnew) + II; {Anew, (1 + m) II, ... |
| I don't know much about Excel, but the simplest type of thing would be to use [Solve][1] or Reduce e.g. Solve[ 24*x==96, x] Note some differences in syntax, especially use "==" for Equal as "=" is reserved for Set. Note that you can use... |
| Probably the starting point would be to find the equations that made the chart, rather than try reproducing equations from the chart. In general, if you are trying to learn something it is worthwhile to implement this yourself, not to implement... |
| You have a syntax error with the parentheses in the last expression, too many closing parentheses in the wrong places. The formula I wrote was a little misleading. When you have a bunch of things there are faster ways to do this, e.g., ... |
| Poll data is probably a new thing, but maybe more appropriate would be the type of experiments done in psychology Or already an old technology is eye tracking. Has anyone tracked the eyes as they see this color representation? Back in 2004... |
| I think Frank is suggesting using [Condition][1] with Rule, see the documentation for examples and don't forget to use "n_" It might work, but if not, then your expression is being automatically transformed before the rule, you might consider... |
| This resource is for everyone, even though the title says it is for programmers. It also has questions to check your understanding. http://www.wolfram.com/language/fast-introduction-for-programmers/ Of course there is a trade off, and this... |
