Torticollis is a problem involving the muscles of the neck that causes the head to tilt down. The term comes from two Latin words: tortus, which means twisted, and collum, which means neck. If your baby has the condition at birth, itâs called congenital muscular torticollis. Thatâs the most common type.
Definition of additive inverse. : a number that when added to a given number gives zero the additive inverse of 4 is â4 â compare opposite 3.
In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x â1, is a number which when multiplied by x yields the multiplicative identity, 1.The multiplicative inverse of a fraction a / b is b / a. For the multiplicative inverse of a real number, divide 1 by the number.For example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.The reciprocal function, the function f (x) that maps x to 1/ x, is one of the simplest examples of a function which is its own inverse (an involution).or example, the reciprocal of 5 is one fifth (1/5 or 0.2), and the reciprocal of 0.25 is 1 divided by 0.25, or 4.
