applying a series expansion such as a Taylor series, and then discarding terms with higher powers of the variable. The order of the approximation is the highest power term that is kept. For example, one can refer to a zeroth-order approximation, a first-order approximation, a second-order approximation, etc. Variations such as zero-order approximation and order-zero approximation are also
