| Dear Dave, this is probably not the solution you are looking for, and it is neither the shortest nor the most elegant one. It is also a Mathematica solution and not a WolframAlpha one. In Mathematica there are symbols with no built-in meaning.... |
| Hi, there is a clue in the error message. {FindRoot[y214862+2y21486-name,{y$21486,0}]} FindRoot attempts to find a root numerically. As you see the error message says that it fails to do so, because there is the variable y (with the... |
| Dear John, do you mean something [like this][1]? ![enter image description here][2] Within Mathematica this might work: {WolframAlpha[ "integrate sin(x)cos(x)^2", {{"IndefiniteIntegral", 1}, "Content"}, PodStates ->... |
| Hi Frank, because the expression is not defined at x=0. You cannot substitute x->0 because you would divide by zero. The limit that you calculate does exist. If you run: FunctionDomain[(x + 1/x), x] You obtain: x 0 The... |
| Well, the Wolfram Language is case sensitive. Try using a capital E and spell Infinity with a capital, too. Cend[x_] := Limit[1/(E^(-x*n) + 1), n -> Infinity] If you then evaluate the function for x->1 you'll get your result. Cheers, ... |
| Dear Mike, it is true that the newer versions of OSX do not support Nvidia drivers. I do run GPUs only under older versions of OSX. I have had to downgrade one computer to make it work, which is a pain because of a new chip which makes downgrading... |
| Hi I also am having issues with four IFTTT I am was running. They have been running for years and are broken since 31December. Other (non IFTTT-based) processes work as usual. Best wishes, Marco |
| It does appear to work on my computer: Sound[{Play[Sin[1000 t], {t, 0, 1}], Play[Sin[2000 t], {t, 0, 1}]}] ![enter image description here][1] I have attached the wav-file. Cheers, Marco [1]:... |
| Hi, I think that this might work: a = Input["Enter No."]; convert = {} While[a > 0, AppendTo[convert, Mod[a, 2]]; a = Floor[Divide[a, 2]];] Print[Reverse[convert]] But why don't you just use something like: ... |
| Well, in fact you do not even need the Flatten or Partition: Select[# |
