Engineering mathematics forms the foundation of all engineering fields, offering the tools and techniques needed to solve real-world problems in areas like mechanical, electrical, and computer engineering. This syllabus provides a clear and structured overview of key topics, including Probability and Statistics, Linear Algebra, and Calculus and Optimization. It’s designed to guide both students and professionals—whether you’re preparing for exams or applying mathematical concepts in practical situations. The goal is to make learning these essential topics straightforward, meaningful, and relevant to modern engineering applications.
Below is the complete syllabus, structured into three main areas with expanded subtopics. Each subtopic includes a brief description to clarify its scope and relevance.
| Main Topic | Subtopic | Description |
|---|---|---|
| Probability and Statistics | Counting Principles | Permutations (ordered arrangements, P(n,r) = n!/(n-r)!) and combinations (unordered selections, C(n,r) = n!/[r!(n-r)!]) for calculating possibilities. |
| Probability Axioms | Fundamental rules: P(A) ≥ 0, P(S) = 1, P(A ∪ B) = P(A) + P(B) for mutually exclusive events, forming the basis of probability theory. | |
| Sample Space and Events | Sample space (S) as all possible outcomes; events as subsets of S, including simple, compound, and null events. | |
| Independent Events | Events where P(A ∩ B) = P(A)P(B); occurrence of one does not affect the other, e.g., coin flips. | |
| Mutually Exclusive Events | Events with P(A ∩ B) = 0; cannot occur simultaneously, e.g., rolling a 3 or 4 on a die. | |
| Marginal Probability | P(A), the probability of event A regardless of others, computed as ∑ P(A ∩ B_i) over all B_i. | |
| Conditional Probability | P(A|B) = P(A ∩ B)/P(B), probability of A given B has occurred, reducing the sample space. | |
| Joint Probability | P(A ∩ B), probability of A and B occurring; P(A)P(B|A) for dependent, P(A)P(B) for independent. | |
| Bayes’ Theorem | P(A|B) = [P(B|A)P(A)]/P(B), used to update probabilities based on new evidence. | |
| Random Variables | Functions mapping outcomes to numbers; discrete (countable values) and continuous (infinite values). | |
| Discrete Distributions | Uniform (equal probabilities), Bernoulli (binary outcomes), Binomial (successes in n trials). | |
| Continuous Distributions | Uniform, Exponential (time between events), Poisson (event counts), Normal, t-Distribution, Chi-Squared. | |
| Cumulative Distribution Function (CDF) | F(x) = P(X ≤ x), gives cumulative probability up to x for discrete or continuous variables. | |
| Conditional PDF | f(x|y) = f(x,y)/f_Y(y), probability density of X given Y for continuous variables. | |
| Descriptive Statistics | Mean (μ = E[X]), median (middle value), mode (most frequent), variance (σ²), standard deviation (σ). | |
| Correlation and Covariance | Correlation measures linear relationship; Cov(X,Y) = E[(X – μ_X)(Y – μ_Y)] quantifies dependence. | |
| Central Limit Theorem and Statistical Tests | CLT: Sample mean approaches normal for large n; Tests: z-test, t-test, chi-squared for hypothesis testing and confidence intervals. | |
| Linear Algebra | Vector Spaces | Sets closed under addition and scalar multiplication, e.g., ℝ^n; basis for linear systems. |
| Subspaces | Subsets of vector spaces that are themselves vector spaces, e.g., span of vectors. | |
| Linear Dependence/Independence | Vectors independent if no non-trivial linear combination is zero; determines basis. | |
| Matrices and Types | Square, diagonal, projection (P² = P), orthogonal (A^T A = I), idempotent (A² = A), partition matrices. | |
| Matrix Properties | Determinant (invertibility), rank (independent columns), nullity (dimension of null space). | |
| Systems of Linear Equations | Ax = b; solved via Gaussian elimination, Cramer’s rule, or matrix inverses. | |
| Eigenvalues and Eigenvectors | Av = λv; used in stability analysis, vibrations, and data compression. | |
| Quadratic Forms | x^T A x; classifies surfaces, used in optimization and control theory. | |
| Matrix Decompositions | LU (A = LU for solving systems), Singular Value Decomposition (A = UΣV^T for data analysis). | |
| Projections | Orthogonal projection onto subspaces, e.g., P = A(A^T A)^(-1)A^T for column space. | |
| Inverse and Adjoint | Inverse: A^(-1)A = I; Adjoint: matrix of cofactors, used in A^(-1) = adj(A)/det(A). | |
| Orthogonalization | Gram-Schmidt process to create orthogonal basis; used in QR decomposition. | |
| Calculus and Optimization | Functions of a Single Variable | Mappings f: ℝ → ℝ, e.g., f(x) = x²; foundation for calculus. |
| Limits | lim(x→a) f(x); describes function behavior as x approaches a. | |
| Continuity | f(x) continuous if lim(x→c) f(x) = f(c); no breaks in graph. | |
| Differentiability | f'(x) = lim(h→0) [f(x+h) – f(x)]/h; measures rate of change. | |
| Taylor Series | f(x) ≈ ∑ [f^(n)(a)/n!] (x-a)^n; approximates functions near a point. | |
| Maxima and Minima | Critical points where f'(x) = 0; second derivative test for concavity. | |
| Optimization | Maximize/minimize f(x); solve f'(x) = 0 for critical points. | |
| Integration | Definite ∫[a,b] f(x)dx (area), indefinite ∫ f(x)dx (antiderivative). | |
| Partial Derivatives | ∂f/∂x for f(x,y); rate of change in one variable holding others constant. | |
| Gradient and Hessian | Gradient ∇f for steepest ascent; Hessian for second-order behavior. | |
| Constrained Optimization | Lagrange multipliers to optimize f(x) subject to g(x) = 0. | |
| Multivariable Calculus | Multiple integrals, vector calculus (divergence, curl) for fields. |
