Continuity And Differentiability Exemplar Solutions - Class 12 Maths

Collegedunia's Class 12 Maths Exemplar Solutions for Chapter 5 walk through every objective and subjective question step by step, with each derivation written in full so that the chain rule, logarithmic differentiation, parametric forms, and second-order derivatives become muscle memory before exams.

Why these Exemplar solutions matter: CBSE 2024 and 2025 board papers borrowed 2 questions verbatim from the Exemplar bank. JEE Main 2024 January session repeated a derivative-of-inverse-trig problem from this very chapter's Exemplar. Solving every Exemplar problem here gives you a 90%+ confidence margin on Continuity & Differentiability.

NCERT Exemplar Solutions for Class 12 Maths Chapter 5 Continuity and Differentiability

The Exemplar for the NCERT Exemplar Class 12 Maths Continuity and Differentiability is organised into five solution categories that mirror the CBSE blueprint. Each category targets a different skill level - the MCQ block tests definition recall, the SA block tests calculation speed, and the LA block tests proof-style reasoning needed for the 5-mark questions on the board paper.

Key Concepts Tested in Class 12 Maths Chapter 5 Exemplar

The NCERT Exemplar Class 12 Maths Continuity and Differentiability address this in the same order as the NCERT textbook.

Before opening the Exemplar PDF, students should be confident with these six anchor concepts. The Exemplar problems are deliberately designed to combine two or three of them in a single question, so weak spots get exposed quickly.

  • Continuity at a point using the three-step test: x → a- f(x) = x → a+ f(x) = f(a)
  • Differentiability implies continuity, but the converse is false (Exemplar Q.28 tests this directly)
  • Chain rule for composite functions: ddxf(g(x)) = f'(g(x)) · g'(x)
  • Logarithmic differentiation for y = [f(x)]g(x) forms
  • Parametric differentiation: dydx = dy/dtdx/dt
  • Mean Value Theorem and Rolle's Theorem - Exemplar reserves 3 LA questions specifically for these

How Collegedunia's Exemplar Solutions Help Class 12 Students Score Better

The NCERT Exemplar Class 12 Maths Continuity and Differentiability address this in the same order as the NCERT textbook.

Most students hit a wall when the Exemplar moves from textbook-style differentiation to mixed problems combining inverse trig with logarithms or parametric forms. Our solutions don't skip algebra steps - every substitution and every cancellation is shown so that you build the same step-by-step muscle the board examiner rewards in 5-mark questions.

What you get inside the Exemplar Solutions PDF:
  • All 58 Exemplar problems solved with full reasoning, not just final answers
  • Method-of-choice notes (when to prefer log differentiation vs chain rule)
  • Common-mistake callouts on every problem with a known trap
  • Alternate methods on long-answer questions where multiple approaches exist
  • Quick-recall formula strip at the start of each section

Sample Exemplar Problem Walkthrough: Differentiability at a Point

The NCERT Exemplar Class 12 Maths Continuity and Differentiability address this in the same order as the NCERT textbook.

A representative Exemplar SA question asks: Show that the function f(x) = |x - 3| is continuous but not differentiable at x = 3. Our solution lays out both halves of the proof end to end so the student sees exactly what an examiner expects.

Step 1 (Continuity): Evaluate left limit, right limit, and f(3) . All three equal 0, so f is continuous at x = 3.

Step 2 (Differentiability): Compute left-hand derivative = -1 and right-hand derivative = +1 . Since LHD ≠ RHD, f is not differentiable at x = 3.

This single problem covers both halves of the NCERT Exemplar Class 12 Maths Continuity and Differentiability title and is exactly the template CBSE uses for 3-mark questions in the Boards.

Common Mistakes Students Make in Continuity and Differentiability

The NCERT Exemplar Class 12 Maths Continuity and Differentiability are written in formal mathematical notation, line by line, in the same convention as the official NCERT print.

  • Forgetting to check f(a) is defined before checking the two-sided limit - students lose 1 mark on a 3-mark continuity question for this.
  • Applying chain rule but missing the inner derivative on inverse trig functions.
  • Confusing e x and 10 x in differentiation rules.
  • Not simplifying inverse trig expressions before differentiation (e.g. tan-12x1-x2 = 2tan-1 x ).
  • Skipping the LHD = RHD check when asked to prove differentiability at a corner point.
