EDEXCEL IAL Pure Mathematics 2 syllabus has included this new topic in the latest specification. his video explains how to prove a conjecture by two methods- Exhaustion & Deduction. In the first example table, the value "7" in the 3rd column is wrong! Its 6 and its obvious but still mentioned the mistake here to avoid confusion. 0:00 - Exhaustion [Example 1] 4:40 - Deduction [Example 1] 8:48 - Exhaustion [Example 2] 9:56 - Deduction [Example 2] #Edexcel #pearson #IAL #Alevel #P2 #AS #Puremathematics2 #proof #proofbyexhaustion #exhaustion #proofbydeduction #deduction #even #odd #divisibility #notdivisible #squarenumbers #algebraicmethods #newspecifcation #IALnewspecification
