I just need a way to express this in a more solvable format...\[\\textup{find}A^{-1}\textup{if}A=begin{pmatrix}a_1&a_2&a_3&\cdots&a_n\\a_n&a_1&a_2&\cdots&a_{n-1}\\a_{n-1}&a_n&a_1&\cdots&a_{n-2}\\\vdots&\vdots&\vdots&\vdots&\vdots\\a_2&a_3&a_4&\cdots&a_1\end{pmatrix}\]
\[begin{pmatrix}a_1&a_2&a_3&\cdots&a_n\\a_n&a_1&a_2&\cdots&a_{n-1}\\a_{n-1}&a_n&a_1&\cdots&a_{n-2}\\\vdots&\vdots&\vdots&\vdots&\vdots\\a_2&a_3&a_4&\cdots&a_1\end{pmatrix}\]
:| Give me a while to solve these TeX issues,
I'll wait. :)
I don't know what's wrong... does this site not have the environment to support the argument pmatrix? stackexchange doesn't, so I suppose it doesn't surprise me that much. :(
hey bad maybe you should report that into the feedback section
Yay! I got it!\[A=\begin{bmatrix}a_1&a_2&a_3&\cdots&a_n\\a_n&a_1&a_2&\cdots&a_{n-1}\\a_{n-1}&a_n&a_1&\cdots&a_{n-2}\\\vdots&\vdots&\vdots&\vdots&\vdots\\a_2&a_3&a_4&\cdots&a_1\end{bmatrix}\]
The question is "find the inverse" but I'd like to solve it myself. Right now, though, I don't know where to start.
you sure that pattern is right? those numbers in the matrix don't seem to have a rule about them
oh nevermind, I see it
I'll work on this tomorrow, and get back to this if I figure out how to do it.
I'm glad you feel pressured to solve this. :P
Blah, I'm going to sleep, then coming back later.
