Mathematics is called as an interesting subject and students can refer to the West Bengal Board Class 12 Maths Syllabus to understand the concepts. An equation or an expression written using Mathematical notation can be read and understood by anyone across the globe. Thus, having and firm foundation in Mathematics will benefit the student to a greater extent in developing problem-solving skills, Mathematical modelling and also in understanding allied subjects. Students can refer to the WBCHSE Class 12 Maths Syllabus to get an overview of the topics and concepts taught in Class for the current academic year.

West Bengal board class 12 mathematics syllabus is prescribed by the West Bengal Council of Higher Secondary Education, commonly called as WBCHSE. The board was formed during the year 1975 and focuses on establishing quality higher secondary education in the state of West Bengal.

WBCHSE Class 12 Mathematics Syllabus enfolds diverse topics from Algebra, coordinate geometry, differential calculus, integral calculus, differential equations, application of calculus. The prime concepts studied here includes – Probability, principle mathematical induction, Binomial theorem for a positive integral index, infinite series, matrices and determinants, cones, parabola, elipse, hyperbola, differential calculus, indefinite integral, integration by parts, definite integral, differential equations, Tangent and normal, maxima and minima, determination of areas in simple cases, expression for velocity and acceleration etc.
