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.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783659947117\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783659947117","offer_id":39450952368221,"sku":"9783659947117","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/ceeedf0b-c8e5-4e41-827e-02a026c59e6d.jpg?v=1773384684","url":"https:\/\/shop.autorenwelt.de\/products\/non-negative-in-value-absolute-in-functionthe-cogent-value-function-von-william-gilreath","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
