reciprocal
意味: A quantity obtained by dividing one by a given number or expression, or an adjective describing something given or felt mutually by both sides.
In mathematics, the reciprocal of a number n is 1/n, such that multiplying a number by its reciprocal always yields one. The concept extends to reciprocal functions and matrices in advanced mathematics. In general usage, reciprocal describes mutual actions or arrangements, as in reciprocal agreements or reciprocal respect between colleagues.
