(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

how does one solve the following equation to obtain E as a function of K.

2. Relevant equations

cos(k*a)=P*sin(u*a)/u*a + cos(u*a),

where u=sqrt(2*m*E)/h-bar

3. The attempt at a solution

theres no way this can be solved analytically,however how to go about approximating E as a function of k.

E(k) is obviously a many to one function.
