Why does it matter what method is used? The uniroot function used a quicker method than bisection, but solves the same problem, so why do you need bisection? The only reason I can think is this is a homework problem, in which case we don't do homework.
In fact I have assigned this as homework before (to write a function to find roots using bisection) so I know it has been done, and is not that hard for you to do yourself. -- Gregory (Greg) L.
