No of Credits: 3

Prerequisites: MAIR11, MAIR21

Course Type: GIR (General Institute Requirements)

Learning Objectives: Objective of the course is to introduce and study

  1. the system of real numbers and their properties like GLB, LUB properties, Archimedian property, density, countability and uncountability

  2. the limit of a function at a point, the limit of a sequence, and the Cauchy criterion in a metric space settings, limit points, compactness, Bolzano-Weierstrass and Heine-Borel properties.

  3. the notions of continuity and differentiability of functions several variables, mean value theorems for these functions

  4. the Riemann integrable functions of real valued functions

  5. sequence and series of functions, and their (pointwise and uniform) convergences

  6. how PDE arise, solutions of certain first order PDE, seperation of variables method, and its use in the solutions of Laplace and Helmholtz equations.

Syllabus: Real number system. Sets, relations and functions. Properties of real numbers.

Sequences. Cauchy sequences. Bolzano-Weierstrass and Heine-Borel properties.

Functions of real variables. Limits, continuity and differentiability. Taylor’s formula. Implicit and inverse function theorems. Extrema of functions.

Reimann integral. Mean value theorems. Differentiation under integral sign. Improper and multiple integrals. Change-of-variables formula. Sequences and series of functions. Pointwise and uniform convergence. Power series and Taylor series.

Laplace and Helmholtz equations. Boundary and initial value problems. Solution by separation of variables and eigen function expansion.

Learning Outcomes: On completion of the course, students should be able to

  1. discuss the convergence of sequences of real numbers.

  2. define the limit of a function , the limit of a sequence, and use the Cauchy criterion

  3. prove theorems about limit of sequences and functions

  4. define continuity/uniform continuity of a function and prove a theorem about continuous functions
