Truncate of order n : truncate
truncate takes as argument, a polynomial and an integer
n.
truncate truncates this polynomial at order n (removing
all terms of order greater or equal to n+1).
truncate may be used to transform a series expansion into a
polynomial or to compute series expansion step by step.
Input :
truncate((1+x+x^
2/2)^
3,4)
Output :
(9*x^
4+16*x^
3+18*x^
2+12*x+4)/4
Input :
truncate(series(sin(x)),4)
Output :
(-x^
3-(-6)*x)/6
Note that the returned polynomial is normalized.
