Continuity and Differentiability (Class 12 Maths): The Checks That Actually Score
Mathematics · Class 12 Continuity and Differentiability (Class 12 Maths): The Checks That Actually Score Most marks in this chapter are lost not on the calculus but on failing to test the one point where the definition of the function changes. Class 12 · Mathematics · Method The short answer: Continuity at a point needs three things to agree — the left limit, the right limit and the value of the function. Differentiability needs the left and right derivatives to agree as well. Every question in this chapter is a version of that test applied at the point where the…
