What kind of Questions can be asked from various topics in Maths?Let’s try to understand.
Dear math scholars
While making Sample Papers for class 12, I had to take immense care about what kind of questions to put in these papers. I discussed with many of my colleagues, senior faculties having experience of over two-three decades and with some CBSE stake holders as well.
Due to the outbreak of pandemic this session, CBSE has reduced syllabus for 2020-21. It has caused a bit of confusion among math teachers in some chapters. Note that CBSE has only mentioned which topics are to be studied this session – means, the Board didn’t issue a specific list of questions from each chapter which may not be asked in the final exams. As far as my understanding, CBSE may test students on any questions – provided we have an alternative solution, within the boundations of reduced syllabus.
For example, many teachers are of the view that question like, Show that tan-1(1/2)+tan-1(1/3)=𝝅/4 is not in syllabus now – as Properties of inverse trig. functions are deleted.
But with an alternative approach, these questions can still be asked in CBSE 2021 Exams. Can you think of an approach other than using properties, for the above question?
My view is same for other chapters and related questions, where alternative approach can be used.
So, I advocate teaching anything and everything that you used to teach. And, leave only those topics and related questions where there is no confusion.
For example, linear differential equations of the form dx/dy + P(y) x = Q(y) are deleted. It has no confusion, so we can skip it.
But, then consider this question : Solve the differential equation (x – y) (dy/dx) = 1. What do you think about it? Is it in syllabus for 2020-21 or not? Well, if you think it is not in syllabus as the given differential equation is Linear D.E. in x then, please check Q24 in my test PTS 04 and its Solutions at this link.
As much as I hate to admit it, I am not perfect. Though I have put in my best efforts and intentions to understand this syllabus reduction proposed by CBSE. Still I believe that my apprehensions may need improvements. Please feel free to offer your constructive suggestions to understand these aspects. Let’s have a healthy discussion.
