CBSE Class 12th Maths syllabus 2019. The Central Board of Secondary Education (CBSE) will conduct board examinations from February for the coming academic year 2019. The board has already released a list of vocational subjects for the examinations that will be conducted from February to March 2019, the schedule and date of the examinations will be released later.
Apart from the 40 different vocational subjects, the board will conduct exams for typography and Computer Applications (English), web applications, graphics, office communication, et al, in February as these subjects have larger practical component, and shorter theory papers.

Appendix 1. Proofs in Mathematics
Through a variety of examples related to mathematics and already familiar to the learner, bring out different kinds of proofs: direct, contrapositive, by contradiction, by counter-example.
2. Mathematical Modelling
Modeling real-life problems where many constraints may really need to be ignored (continuing from Class XI). However, now the models concerned would use techniques/results of matrices, calculus, and linear programming.
