I would like to know if there any analytical methods that can be used to solve this equation. So far, I've made the following observations:
- We have to only check for solutions within the domain $-1/m\leq x\leq1/m.$
- More than one solution is possible when $0\leq |m|<1.$
I am also guessing that if the slope $0<m\leq \frac{2}{(4n+1)\pi}$ where $n$ is whole number, then the number of solutions $x>0$ will be $2n.$
