New and updated content (Class 11 NCERT)

I request you to please update the courses especially for class 11 NCERT, of which I am aware they aren't updated as I was studying from them. Do keep the old stuff there even if it is out of syllabus but add all the new things. E.g.: In chapter 3, 'Vectors prerequisite' the dot and cross properties of vectors is missing, some derivations which are on the NCERT book are missing. In chapter 2, the derivation of Equations of motion through Calculus method is missing. Please, revisit the NCERT books and add the missing portions so that we can stick to one source and it matches what we study in school.
