Title  Description  

Washer  Essentially the same as a cylinder, the Washer method for integrating a volume of revolution in calculus employs a thin, hollow disk as the partition of integration. 

Wavelength  The length of a wave, literally, is its Wavelength. Typically symbolized with Greek letter lambda, a Wavelength can be measured by actual length, or by the period, which may be the angle traversed through one complete cycle, or the time required to complete a cycle. 

Weighted Average  When several factors comprise a score or calculation and the factors have different amounts of importance to the overall result, a Weighted Average may be calculated by assigning more importance (or "weight") to one factor over another. 

Whole Numbers  Most often, the set of positive integers and zero. 

Work  Equivalent to energy, Work is the product of force and distance.
