About this previous year paper
This question paper is designed to evaluate a student’s understanding of advanced engineering mathematics topics including Laplace transforms, Fourier analysis, algebraic structures, Boolean algebra, recurrence relations, and lattice theory. The paper is structured into three comprehensive sections to test conceptual clarity, analytical ability, and problem-solving skills.
SECTION A – Short Answer Type Questions (20 Marks)
This section contains 10 brief questions, each carrying 2 marks.
These questions focus on:
Fundamental definitions (unit cell, ring, equivalence relations, etc.)
Basic computations (Laplace transform, Fourier transform)
Conceptual understanding of algebraic structures
Drawing Hasse diagrams
Applying basic theorems (Lagrange’s theorem, equivalence relations, etc.)
This section tests the core concepts and ensures the student understands foundational principles.
SECTION B – Descriptive / Analytical Questions (30 Marks)
Students must attempt any 3 out of 5 questions, each of 10 marks.
This section includes:
Proof-based mathematical questions
Group theory applications
Recurrence relations
Boolean algebra (DNF form)
Fourier and inverse Fourier transforms
The purpose of Section B is to assess analytical thinking, logical reasoning, and the ability to apply mathematical theorems.
SECTION C – Long Answer / Problem-Solving Questions (50 Marks)
This section contains 7 questions, out of which the student must attempt one part from each question.
Each carries 10 marks.
This section covers:
Differential equations solved using Laplace transforms
Z-transform for difference equations
Boolean logic using truth tables, K-map, and switching circuits
Induction proofs
Solving congruences
Advanced recurrence relations
Lattice theory and distributive laws
This section deeply evaluates the student's problem-solving ability, mathematical maturity, and understanding of higher-level concepts.
Overall Purpose of the Question Paper
This question paper aims to:
Test conceptual clarity in engineering mathematics
Strengthen analytical and algebraic reasoning
Evaluate proficiency in transforms (Laplace, Z, Fourier)
Assess the ability to handle discrete structures
Examine logical reasoning and Boolean algebra applications
Measure the student’s ability to solve structured long problems
It is carefully crafted to ensure students demonstrate both breadth and depth of knowledge across multiple mathematical domains essential for engineering studies.
