Lowerorder
Lower-order term, in mathematics, refers to any term that grows more slowly than the leading term of a function as its variable becomes large, or, in the context of differential equations, to terms involving lower-order derivatives relative to the highest derivative present. The exact meaning depends on the comparison used, such as a polynomial degree or the order of differentiation, and is often clarified by the surrounding terms being considered.
In polynomials, the leading term is the one with the highest degree, and all other terms are
In differential equations, the notion also applies to derivatives: in an equation of order m, the term
Overall, the concept of lower-order terms is relative and context-dependent, serving as a useful way to distinguish
