CBSE Syllabus of Class 12th MATH 2022-2023:

In the 12th science curriculum, mathematics is divided into two main categories – Pure Mathematics and Applied Mathematics. Pure Mathematics covers topics such as calculus, algebra, and geometry, while Applied Mathematics includes topics such as statistics, probability, and numerical analysis. Students in the 12th science curriculum are exposed to a wide range of mathematical concepts and principles, including functions, limits, differentiation, integration, trigonometry, matrices, determinants, vectors, and probability.
