Inversion tables decompress the spine and reduce the pressure on it, which can relieve back pain. Additional benefits include reducing muscle spasms, improving circulation and stretching the body.

The multiplicative inverse of a number is the number by which it can be multiplied to yield 1. It is also known as the reciprocal of a number.

The derivative of an inverse function is a calculation of the slope at a particular point of a function that acts in the reverse manner of another function. It is typically denoted as the function f(x) taken to the power of negative one, followed by an apostrophe.

A T-wave inversion indicates the presence of many cardiac and noncardiac issues. The American Heart Association states that T-wave inversions are found in children, but generally they are not seen in healthy adults.

Atmospheric inversion is when the temperature in the atmosphere inverts, making the temperature rise instead of fall in areas higher above the ground. Inversions occur most commonly in the afternoon due to the ground emitting more radiation than it is receiving from the waning sunlight.

Atmospheric inversions are parallel layers of air that rise in temperature as they get higher. This warm air is light and lies over cool and heavy air, which makes this air have strong upright stability, particularly when there are no strong winds.

A direct variation graph represents a situation in which two variables increase or decrease at the exact same rate. The line on the graph is a straight line that passes through the origin of the graph. The origin is the point on the graph where the horizontal and vertical axes intersect.

In math, inverse is explained as the opposite in effect. An inverse function is one that reverses another function. If an inverse does exist for a function, it is referred to as an invertible function.

The opposite of an inverse relationship is a direct relationship. Two or more physical quantities may have an inverse relationship or a direct relationship. Temperature and pressure have a direct relationship, whereas volume and pressure have an inverse relationship.

The general formula for an inversely proportional relationship is y = k/x, where k is the constant of proportionality and x is an independent variable. In an inversely proportional relationship, the value of y decreases as x increases or increases as x decreases.
