However, one property of the absolute value function is that it is discontinuous or non-differentiable at zero. The cogent value function is the alternative to the absolute value function, exactly like the absolute value function only defined differently, so having a different set of mathematical properties. Most importantly, the cogent value function is differentiable at zero--which changes the mathematical utility of the absolute value function, and opens possibilities in prior existing, and future mathematics.","brand":"LAP LAMBERT Academic Publishing","offers":[{"title":"Default Title","offer_id":54725286363478,"sku":null,"price":0.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0925\/5829\/5382\/files\/product_image_9783659947117_1.jpg?v=1791093088","url":"https:\/\/www.momoxbooks.com\/de\/products\/gilreath-william-non-negative-in-value-absolute-in-functionthe-cogent-value-function-9783659947117","provider":"momox","version":"1.0","type":"link"}
