Answer
Dear Sir
I have the following queries regarding the revised syllabus of CBSE class 12 Maths
1) NCERT Chapter 12 : Linear Programming : The deleted Syllabus mentions : "Mathematical Formulation of LPP " .
Does this mean that all the word problems and entire Ex.12.2 is deleted from the syllabus ?
2) NCERT Chapter 8 : Applications of Integrals
The deleted Syllabus mentions "Area between Two Curves " .
As per my observation NCERT Ex.8.1 includes such questions based on Area between a curve and a line (given equation of lines in two variables which is considered to be under Curves category ) (Q.6,Q.9,Q.10). So do we have to prepare these questions of Ex.8.1 or exclude ?
Further, Ex.8.2 includes questions based on Area between a curve and a line (given equations of lines in two variables) (Q.3,Q.6,Q.7) and also the questions related to area within a triangular region. (given vertices of a triangle or equations of lines of a triangle in two variables form ) (Q,4,Q.5).
This creates utmost confusion in filtering questions of Ex.8.1, Ex.8.2 and Misc. Ex.of chapter 8.
I request you to guide me with appropriate Question Numbers that are deleted.
3) Chp.4 Determinants Ex.4.2 is deleted or not (as properties of determinants are deleted).
Please reply as soon as possible.
Thanks and Regards,
Falguni Shah.
