I want to solve transcendental equations by Mathematica 7. Solve does not help me, reduce - as well. Seams that I shoulkd use FindRoot, but it does not give all solutions. It gives only one solution. So how can I solve transcendental equations?
Here is the equation I want to solve:
So for a fixed value of L, A1, A2 (L >= 0 and is an integer) parameters I want to find all values for k expressed with A1 and A2, for which the determinant is 0. In addition I must say that A1 and A2 >0.
