NSolve to find the roots to a transcendental equation. For this, I need to specify a bounded region where roots are searched. What I want to know is how
NSolve mathematically finds these roots, and why I need to specify a bounded region.
When I look up
NSolve on Mathematica all it says is that
NSolve[expr, vars]: attempts to find numerical approximations to the solutions of the system expr of equations or inequalities for the variables vars
It doesn't tell me anything about how it does this. If it is using Newton-Raphson's method or any other method?
