(SEM I) THEORY EXAMINATION 2017-18 ENGINEERING MATHE MATICS
This document contains a comprehensive Engineering Mathematics question paper designed as per B.Tech university examination standards. The paper is divided into Section A, B, and C, covering a complete range of topics from calculus, matrices, vector calculus, multiple integrals, curve tracing, and differential equations.
It is ideal for AKTU, VTU, JNTU, BTU, MAKAUT, CU, DU, RTU, and all B.Tech first-year students.
SECTION A – Short Answer Questions (2 × 7 = 14 Marks)
Includes fundamental questions from:
nth derivatives of algebraic–logarithmic functions
Double integrals
Jacobians and partial derivatives
Area bounded by curves
Error propagation
Solenoidal vector conditions
Matrix reduction & rank determination
These questions test theoretical understanding and quick calculation skills.
SECTION B – Analytical Questions (7 × 3 = 21 Marks)
Covers medium-level problems from:
Higher Order Derivatives
Differential coefficients of trigonometric combinations
Euler-type derivative identities
Matrices and Determinants
Rank of matrices using row transformations
Matrix inverse using elementary operations
Jacobian & Partial Derivatives
Transformation of variables
Functional relations among variables
Multiple Integrals
Change of order of integration
Beta & Gamma function properties
Vector Calculus
Irrotational fields

These questions strengthen concept clarity and procedural methods.
SECTION C – Long Answer Questions (7 × 5 = 35 Marks)
Includes advanced, exam-focused topics:
1. Differential Calculus & Differential Equations
Recurrence relations for higher derivatives
Mixed partial derivative identities
Curve tracing techniques
2. Maxima, Minima & Approximation
Lagrange multipliers
Differentials in geometrical applications
Multivariable Taylor's expansion
3. Linear Algebra
