WebFeb 22, 2012 · FindRoot, one of the functions you used, solves numerically only, iterating Newton's method until sufficiently accurate. Root is, as far as I know, not really meant to find roots, it's much more an abstract representation of the n th root of an equation, much like sin ( 10) does make sense on its own, without evaluating it to an explcit number. exploding backpack
