What is define reciprocal?

In mathematics, the reciprocal of a number is its multiplicative inverse. In other words, it is a number that, when multiplied by the original number, yields a product of 1. For example, the reciprocal of 2 is 1/2, because 2 multiplied by (1/2) equals 1. The reciprocal of a fraction is simply its inverse, obtained by swapping the numerator and denominator. Algebraically, the reciprocal of a number x can be expressed as 1/x or x^-1. The concept of reciprocal plays an important role in many mathematical operations, including division, solving equations, and evaluating trigonometric functions.
