I am trying to find eigenvalues of a matrix. It has two symbols $k_1$ and $k_2$. I get this solution from mathematica

enter image description here

Reading the doucmentation, I know # is a placeholder, much like an input to an expression. But I have no inputs to give.

My interpretation:

There are 4 Roots[expression,number]. I imagine they correspond to the four eigenvalues. The #s represent the supposed input to be filled. What do they refer to?

P.S.: I'd like to point out that my question is more about interpretation. I am not able to understand the way #s are defined in mathematica and solution given here!

  • Whaat does ANCL mean? – bobbym Sep 24 '16 at 05:47
  • correct me if I am wrong but the root post deals with finding solution to radical or trancendental equations. I think mine is a radical one. Although the post did help me in understanding how the roots are given in pure functions, I still cannot understand how to identify what this solution represents. e.g. I would expect it to give me something like fourth root of k1 - something. That can be understood but in this I see k1 and k2 separate, then what needs to fo in #. maybe I dont still understand the concept of pure fucntions – Zero Sep 24 '16 at 11:58
