Feature Request: Function Panel
|
| |
In the function panel please tell what and how the arguments are supplied. For example, I have just spent 10 mins trying unsuccessfully to use binompmf which gives an error for binompmf(0.4;4;10), and other variations I have tried. By the way, Matlab has a similar annoying feature. SUGGESTION: When I double click on a function name show the function... more »

Google and Wolfram Alpha API integration
|
| |
I just found a great addon for Google Chrome called "Chromey Calculator". It processes its math directly from Google and Wolfram Alpha. The problem is the lack of variables and the millions of other features that Speedcrunch has. However, I thought it would be pretty cool if, on some level, Speedcrunch could use Wolfram Alpha as a back-end processor for certain... more »

Data list (14;13;12;11;10;9;8;7;6;5)
Freq list (1;2;3;3;5;3;2;1;2;1)
n=23 or sum( Freq list)
sum of data should be Data list x Freq list (each number of list -
position one of each list multiplied , then position two
multiplied, ...
then summed. mean is sum / n mean = 9.8261...
sum is 226
then each item in combined list squared (sx^2) = 2346... more »
