संकल्पना:

स्क्वीज़ प्रमेय (सैंडविच प्रमेय): इसका प्रयोग एक फलन पर तब किया जाता है जहाँ इसका अवकलज करना लगभग असंभव होगा। 

  • स्क्वीज़ प्रमेय बताता है कि यदि हम फलन को इस प्रकार परिभाषित करते हैं जिससे h(x) ≤ f(x) ≤ g(x) है और यदि \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\), है, तो \(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)  है।
