Course Objectives :

The course aims to acquaint the students with the fundamentals of analytical mathematics and their use in some important applications of chemistry (e.g. Huckel theory, maximally populated rotational energy levels and Bohr’s radius). This course also aims to make the students aware about the concept of matrix properties, calculus, probability and elementary differential equation (first order & first degree).

Mathematics for Chemists

The students will be able to-

CO21-employ basic operations like addition, multiplication, transpose, inverse and determinant of matrices.

CO22-differentiate one variable function up to a higher order, two variable functions up to second order.

CO23-apply the basic rules of integration on one variable function and product of one variable functions.

CO24-analyze the simple problems of permutation, combination and probability and concept of scalers and vectors and their operations.

CO25-distinguish between the concept of order and degree of differential equation and solution of first order and first degree linear differential equation.
