When computing the series expansions, you get expressions with
one of the terms represented as the Landau symbol
O. This term shows the
truncation order (error order) of the computed series expansion.
MuPAD® automatically simplifies the
O(10*x^7 + 20*x^8), O(x^2 + x + 1), O(x^3*y^2 + x^2*y^2)
When evaluating expressions with order terms, the system uses standard arithmetical operations for these terms:
O(x^3)/O(x^2), O(x^3) + O(x^2), O(x^3)*O(x^2)
