My solution: http://snk066.tk/math/my_solution.jpg
What you need to? I need an answer in the form: u (x,t) = (some polynomial)
The solution is not really necessary, if someone will explain-thank you, but if there are calculators that believe this, one answer will do.
I tried to decide for myself, it did not work. The problem consists in obtaining the values of the constants. The integration and expression of these constants, where is trigonometry, they're just not expressed, maybe under the cosines of the bad roots.
