Is there any way to enter tetration in WolframAlpha, in such a way that I can use it with the limit function? More specific, can I make Wolfram Alpha calculate the limit of sqrt(2)^sqrt(2)^sqrt(2)^sqrt(2)^... You get it? And i know it will be 2, i just wanted to ask for the general case.Alexander Wolters2017-07-17T18:27:36ZWhat is the difference between wolfram alpha (app) vs wolfram alpha pro?

Wolfram alpha pro shows step by step solutions but so does the app. What is the difference between the two besides the huge price difference?Eduard Ordukhanov2015-10-15T07:18:37ZEigenvalues of a real symmetric matrix
http://community.wolfram.com/groups/-/m/t/1148141
Hello,
I am using Wolfram Alpha widgets for calculating Eigen values of a 3X3 real symmetric matrix. It is known the a real symmetric matrix has real Eigen values.
However, the calculator is giving roots with iota (complex looking roots). So I have two questions,
1) Are the Eigen values computed by the widget actually complex?
2) If eigen values are not complex, then why aren't they simplified and given? How do I simplify them?
The matrix which I used is :
A = [ [ 1 2 3],
[2 1 2],
[3 2 3] ]
Here is the link also,

Thanks in advance. Hoping to hear from you soon.

P.S. : For the above matrix A, real Eigen values are 6.569, -1.342, -0.227.Sandhya Tripathi2017-07-17T06:41:33Z
