Core course for B.Sc. (Research) programs in Mathematics, Physics and Economics. Optional course for B.Sc. (Research) Chemistry.

**Credits (Lec:Tut:Lab)**= 3:1:0 (3 lectures and 1 tutorial weekly)

**Prerequisites: **Class XII mathematics or MAT 020 (Elementary Calculus)

**Overview****:** This course covers one variable calculus and applications. It provides a base for subsequent courses in advanced vector calculus and real analysis as well as for applications in probability, differential equations, optimization, etc. One of the themes of the course is to bring more rigour to the formulas and techniques students may have learned in school.
