I have the following equation that I want to solve with respect to a: x = (a-b-c+d)/log((a-b)/(c-d)) where x, b, c, and d are known. I used Wolfram Alpha to solve the equation, and the result is...

I know that I asked the same question before, but as I am pretty new here the question was asked poorly and not reproducible. Therefore I try to do it better here. (If I only edit the old one proba...

My purpose is to find a eigenvectors of a matrix. In Matlab, there is a [V,D] = eig(M) to get the eigenvectors of matrix by using: [V,D] = eig(M). Alternatively I used the website WolframAlpha to d...

I am trying to query wolfram to do some math for my site and then display the result. I am having trouble with CORS. My Code: var xmlHttp = new XMLHttpRequest(); xmlHttp.onreadystatechange = func...

When I run my python 3 program: exp = 211 p = 199 q = 337 d = (exp ** (-1)) % ((p - 1)*(q - 1)) results in 211^(-1). But when I run the calculation in wolfram alpha I get the result I was expe...

Plotting a function in the wolfram-alpha-website looks like this: http://www.wolframalpha.com/link Plotting the same function in R looks like this: plot( function(x) x^2 - 3*x - 10 ) The def...

I have a list of numbers [1, 2, 3, 4, 5, 6, 7] and I want to have a function to return the interquartile range of this list of numbers. The interquartile range is the difference between the upper a...

688^79 mod 3337 = 1570. When I tried this at wolfram alpha I got: but When I entered the same thing in Matlab, I get 364 as the answer. I got to be doing something wrong. Any light on this w...

How do I get wolfram's api requests to work? I just get cross-origin errors and a blank response: "XMLHttpRequest cannot load http://api.wolframalpha.com/v2/query?input=No&appid=xxx. Origin nul...

I've tried several approaches, such as defining a function f(t) at certain values, and then using f(t) in my equation, but nothing has worked for me thus far. I love using wolfram alpha, it is an i...

When the mouse cursor is over a 2D plot in Wolfram|Alpha, a pair of grey lines appear that help you read the coordinates off the x and y axes. For example, I have the mouse over one of the turning ...

The wolfram alpha web interface suffers (like Mr. Wolfram) from massive hubris. There is some very useful data behind that interface; however, and I'd like to access it programmatically. Ther...
