Why would MATLAB not give a correct answer. From what I can infer, as the nth terms rises the factorial rises dramatically, therefore the fraction becomes very minuscule in value. Ten terms would be sufficient to give an answer correct to the third or fourth decimal place.

I have to find the "second smallest root" of the following equation :
1-x+(x^2)/(2!)^2-(x^3)/(3!)^2+(x^4)/(4!)^2+...=0
Matlab returns quite a satisfactory answer. >> p=[1/518400 -1/14400 1/1576 -1/36 1/4 -1 1]
p =
0.0000 -0.0001 0.0006 -0.0278 0.2500 -1.0000 1.0000...
