,Preface
The Engineering Mathematics and Mathematical Methods in Sciences are the necessary courses
for all engineering and science majors, respectively, that are taught at universities and colleges
worldwide. This textbook has been prepared for instructors as well as for students taking these
courses. In each chapter of the textbook, different types of problems and exercises have been
presented that are categorized as follows.
• Problems with detailed solution: They have been designed to teach students the subjects in
detail. Moreover, they have been categorized in different levels based on their difficulty
levels (easy, normal, and hard) and calculation amounts (small, normal, and large). These
classifications can help students study the book in the most efficient way.
• Partially solved exercises: They have been designed to encourage students to practice more
problems while guiding them through the problem-solving procedure and hinting the
required formulas.
• Exercises with final answer: They have been designed to encourage students to practice by
themselves while hinting them by the final answer as well as to help instructors to give tests
or quizzes.
In the following, the description of each chapter is briefly presented.
Chapters 1 and 2 cover the subjects concerned with the complex quantities, limit of complex
functions, complex equations, and holomorphic functions and their harmonic conjugate
functions.
Chapters 3 and 4 teach the complex transformations that include linear, power, reciprocal,
exponential, natural logarithm, hyperbolic sine and cosine, sine and cosine, and linear fractional
complex transformations.
Chapters 5 and 6 study the singularities of complex functions (such as poles, removable
singularity, and essential singularities), complex series, Taylor and Laurent series expansions of
complex functions, and residue of complex functions.
Chapters 7 and 8 review different complex integrations that include complex integration of
nonholomorphic functions, complex integration of holomorphic functions, and complex inte-
gration of functions including finite number of singular points.
Chapters 9 and 10 investigate the Fourier series of periodic functions, half-domain Fourier
sine and cosine series of aperiodic functions, complex Fourier series of periodic functions,
Fourier integral of aperiodic functions, complex Fourier integral of aperiodic functions, Fourier
transform of aperiodic functions, and half-domain Fourier sine and cosine transforms of
aperiodic functions.
Chapters 11 and 12 are concerned with the determination of type of partial differential
equations, updating partial differential equations by new variables and solving the partial
differential equations. In this regard, the partial differential equations are solved by using
several techniques such as the approaches used in solving ordinary differential equations, the
method of characteristics equation, the technique of variables separation, and Laplace trans-
form. Moreover, solving partial differential equations in the steady-state condition is presented.

If the students have difficulties in studying the textbook, they can first study the calculus
series books covering Precalculus, Calculus I, Calculus II, and Calculus III. The subjects of the
calculus series books are as follows.
Calculus III: Practice Problems, Methods, and Solutions, Springer Nature, 2023.
• Linear Algebra and Analytical Geometry
• Lines, Surfaces, and Vector Functions in Three-Dimensional Coordinate System
• Multivariable Functions
• Double Integrals and Their Applications
• Triple Integrals and Their Applications
• Line Integrals and Their Applications
Calculus II: Practice Problems, Methods, and Solutions, Springer Nature, 2023.
• Applications of Integration
• Sequences and Series and Their Applications
• Polar Coordinate System
• Complex Numbers
Calculus I: Practice Problems, Methods, and Solutions, Springer Nature, 2023.
• Characteristics of Functions
• Trigonometric Equations and Identities
• Limits and Continuities
• Derivatives and Their Applications
• Definite and Indefinite Integrals
Precalculus: Practice Problems, Methods, and Solutions, Springer Nature, 2024.
• Real Number Systems, Exponents and Radicals, and Absolute Values and Inequalities
• Systems of Equations
• Quadratic Equations
• Functions, Algebra of Functions, and Inverse Functions
• Factorization of Polynomials
• Trigonometric and Inverse Trigonometric Functions
• Arithmetic and Geometric Sequences
Since the textbook includes the basic and advanced problems with very detailed problem
solutions, it can be used as a practicing study guide by students and as a supplementary teaching
source by instructors. Moreover, since the problems and exercises have very detailed solutions,
the textbook is helpful for under-prepared students. In addition, it is beneficial for knowledge-
able students because it includes advanced problems and exercises.
In preparing the problems and solutions, care has been taken to use methods typically found
in the primary instructor-recommended textbooks. By considering this key point, the textbook
is in the direction of instructors’ lectures, and the instructors will not see any untaught and
unusual problem solutions in their students’ answer sheets.
