Continuity refers to the smoothness of a function, where there are no sudden jumps or breaks in its graph. Differentiability, on the other hand, deals with the existence of a derivative at a given point, indicating the rate at which the function changes. Understanding these concepts is crucial for solving complex mathematical problems and real-life applications.<\/p>\n<p>MCQs (Multiple Choice Questions) are an effective tool for students preparing for the Class 12 Maths board exam. They help students assess their understanding of continuity and differentiability concepts by offering a range of possible answers. By practicing MCQs, students can identify areas of weakness and focus on improving them.<\/p>\n<p>Additionally, MCQs simulate the exam environment, helping students manage time effectively and develop a strategy for answering questions efficiently. Overall, MCQs play a significant role in helping students ace the Class 12 Maths board exam by providing targeted practice and enhancing conceptual understanding.<\/p>\n<p><strong>Latest: <a href=\"https:\/\/infinitylearn.com\/surge\/cbse\/cbse-class-12-maths-answer-key-2024\/\">CBSE Class 12 Maths Answer Key 2024<\/a> | <a href=\"https:\/\/infinitylearn.com\/surge\/cbse\/cbse-class-12-maths-paper-analysis-2024-out\/\">CBSE Class 12 Maths Paper Analysis 2024<\/a><\/strong><\/p>\n<p><strong>Question 1. <\/strong><strong>The derivative of f(tan x) w.r.t. g(sec x) at x = \\(\\frac{\\pi}{4}\\), where f'(1) = 2 and g'(\u221a2) = 4, is<\/strong><\/p>\n<p><strong>(a) \\(\\frac{1}{\\sqrt{2}}\\)<\/strong><\/p>\n<p><strong>(b) \u221a2<\/strong><\/p>\n<p><strong>(c) 1<\/strong><\/p>\n<p><strong>(d) 0<\/strong><\/p>\n<p><strong>Answer:<\/strong><\/p>\n<p>(a) \\(\\frac{1}{\\sqrt{2}}\\)<\/p>\n<p><strong>Question 2.<\/strong><\/p>\n<p><strong><img loading=\"lazy\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/50354653728_486459141c_o.png\" alt=\"Maths MCQs for Class 12 with Answers Chapter 5 Continuity and Differentiability Q32\" width=\"390\" height=\"236\" \/><\/strong><br \/>\n<strong>Answer:<\/strong><\/p>\n<p>(c) \\(\\frac{2}{3}\\)<\/p>\n<p><strong>Also Refer:<\/strong> <a href=\"https:\/\/infinitylearn.com\/surge\/mcqs\/class-10-maths-areas-related-to-circles\/\"><strong>Areas Related to Circle Class 10 MCQs<\/strong><\/a><\/p>\n<p><strong>Question 3.<\/strong><\/p>\n<p><strong><img loading=\"lazy\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/50355358731_cb940972d3_o.png\" alt=\"Maths MCQs for Class 12 with Answers Chapter 5 Continuity and Differentiability Q33\" width=\"392\" height=\"156\" \/><\/strong><br \/>\n<strong>Answer:<\/strong><\/p>\n<p>(b) 1<\/p>\n<p><strong>Question 5.<\/strong><\/p>\n<p><strong><img loading=\"lazy\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/50355358766_7dbaf6aa2d_o.png\" alt=\"Maths MCQs for Class 12 with Answers Chapter 5 Continuity and Differentiability Q35\" width=\"359\" height=\"123\" \/><\/strong><br \/>\n<strong>Answer:<\/strong><\/p>\n<p>(a) n<sup>2<\/sup>y<\/p>\n<p><strong>Question 6.<\/strong><\/p>\n<p><strong><img loading=\"lazy\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/50355358786_c6dc031c29_o.png\" alt=\"Maths MCQs for Class 12 with Answers Chapter 5 Continuity and Differentiability Q36\" width=\"357\" height=\"162\" \/><\/strong><br \/>\n<strong>Answer:<\/strong><\/p>\n<p>(d) \\(-\\frac{b}{a^{2}} \\sec ^{3} \\theta\\)<\/p>\n<p><strong>Question 7.<\/strong><\/p>\n<p><strong><img loading=\"lazy\" src=\"https:\/\/infinitylearn.com\/surge\/wp-content\/uploads\/2021\/12\/50354653828_f1cb2ec64a_o.png\" alt=\"Maths MCQs for Class 12 with Answers Chapter 5 Continuity and Differentiability Q37\" width=\"297\" height=\"125\" \/><\/strong><br \/>\n<strong>Answer:<\/strong><\/p>\n<p>(c) y.
