Mathematics \ 1-1
Arif Sabuncuoğlu This book can be used as a textbook in the "Analytical Geometry" courses taught in the first (or second) grades of the mathematics and mathematics teaching departments of universities.
In addition to covering the basic subjects that the students studying in these departments will need in the lessons they will study in the advanced classes, it will also help them in the subjects that the prospective teachers will teach while teaching in high schools. These topics are given quite concisely without going into too much detail. The connections between the subjects were fully established and care was taken not to leave any open questions.
After each concept, enough examples are given to explain this concept. A sufficient number of exercises are included at the end of each section to make the subject comprehend. Solutions to all of these exercises have been published as a separate book.
The problems are ordered from easy to difficult, and abstract problems are placed at the end. The problems included in the book are not very specific problems in this field, but rather the type of questions that will be easily understood by the students, will make the students love the Analytical Geometry course and will better understand and reinforce the analytical geometry knowledge that will form the basis of the courses they will read in the advanced grades. The results of the problems and the actions to be taken while obtaining these results have been chosen in a way that will not tire the reader.
Aysun Tezel Özturan Numerical analysis (numerical analysis) consists of methods used to find approximate solutions for problems that cannot be solved analytically or which are very difficult to solve. In recent years, the use of numerical analysis methods has increased in parallel with the developments in the field of computers. Numerical analysis methods are frequently used in many engineering fields and applied sciences.
In this book, numerical analysis methods and their MATLAB applications are explained.
The book consists of ten main chapters:
In the first chapter, the history of numerical analysis, the basic theorems used, machine numbers and errors are included. In the second part, direct and iterative solution methods for linear equation systems are mentioned.

This book is a useful resource for all engineering students using undergraduate and graduate level mathematics, applied mathematics, and numerical analysis.
Ayşe Kökcü Once Upon a Time Geometry is a book that tells the 2500-year history of geometry through breaking points. The most important reason for the difficulties that mathematics students face while learning pure mathematics is that they cannot establish the necessary relationship between the mathematical formulas they learn and the world they live in. Likewise, philosophy students have close thoughts about mathematics and the history of mathematics. First of all, what is wanted to be done with this book is to establish the relationship between philosophy and the history of mathematics through geometry as clearly as possible. Secondly, it is to give an idea about the position of geometry in mathematics and philosophy of mathematics.
Since Euclid's "Elements," geometry has been in a position to promise much more than ground measurement. It is about the objects that are at the center of man's understanding of himself and the universe he lives in.
The main reason for this is that geometry, besides being a type of knowledge produced by the human mind, serves as a key to understanding the universe.
Arif Sabuncuoğlu This book contains solutions to exercises from the author's book “Analytical Geometry”. It is prepared for the benefit of our students in the Analytical Geometry courses taught in the first (or second) grades of universities.
The problems in this book will not only cover the topics that our students will need in the lessons they will study in the advanced grades, but also will help them in the topics that prospective teachers will teach while teaching in high schools. If the solutions of the exercises are included in the "Analytical Geometry" book, it was thought that it would be more appropriate to collect it in a separate book, since the volume of the book would increase a lot.
The problems are ordered from easy to difficult, and abstract problems are placed at the end. The problems included in the book are not very specific problems in this field, but rather the type of questions that can be easily understood by the students, that will make them love the Analytical Geometry course and that will provide a basis for the courses they will read in the advanced classes, and will better understand and reinforce their knowledge of Analytical Geometry. The problems, results and the actions to be taken while obtaining these results have been chosen in a way that will not tire the reader.
Timur Karaçay Thanks to the technological developments in computer hardware, it has been calculated that the life expectancy of a newly emerging language is 10 years on average. All languages ​​make updates and adjustments parallel to the development of hardware and computer science. The language that does not do this job completes its average life span and withdraws from the scene.
Java emerged in the 1995's and has always kept its flagship place. Because Java brought great innovations to computer science. The last version of Java at the time of writing this book was Java 9. Java 9 differs from previous versions; Deep Java 9 describes these differences and innovations.
All versions of Java are backwards compatible up to Java 9. By breaking this rule, Java 9 also brought innovations that are considered revolutionary in the language.
Java 9 continues to support previous versions. This means that Java can be used as is the JCF:Java Collections Framework, which has revolutionized computer science.
Java, which has not lost its place in the flagship since its emergence, will continue to be a robust and reliable language preferred by large enterprises from now on.
This book describes the innovations brought by Java up to version 9. These topics, which are not given much importance in the Introduction to Java lessons, are the hand tools of the professional programmer.
Deep Java 9 is for those with an introductory knowledge of Java. For the non-Java reader, we recommend reading a good java book before starting this one.

Abuzer Gündüz Ring Theory is a theory that is taught in the undergraduate courses of our universities and contains the basic tools of algebraic geometry in general. Its main motivation is to be able to do arithmetic with integers in new ring classes. In this respect, it relies entirely on the ability to think abstractly. Naming things and establishing relationships between them is the starting point of this process. The possibilities these new structures offer us are quite surprising.
In this book, we tried to present the first seven chapters taught at the undergraduate level in as much detail as possible, with clear proofs and solved questions. Secondly, we have written the last four chapters for undergraduate and graduate students who want to do research on these topics. Our main goal is to get them to the level where they can read articles on this subject.
We hope that the reader will develop reasoning skills and acquire the habit of proving by trying to solve the solved questions and the end-of-chapter questions.
Hope the book will be useful to all readers...

Alattin Ural From the micro level to the macro level, there is a dynamic order in life and the universe, even if it seems chaotic, and mathematics is an important tool in analyzing and expressing this order. The mathematical information revealed by the branches of science explaining nature and the universe and the information revealed by mathematics itself are in harmony within and between themselves. In short, where there is order of any kind, there is also mathematics.
Basic knowledge and skills that should be used in daily life such as measuring (number, length, area, volume, time) and calculating (shopping, determining the requirements for the completion of a job, sharing, finding direction, determining relationships, etc.) mark the emergence of mathematics. motivated. Therefore, before mathematical concepts and operations were defined, they were felt in life and the mental infrastructure of discovery was formed. When we consider numbers, shapes and properties, solving real life problems with a mathematical potential, and generally being able to reveal the solution methods to problems, as a mathematical thinking skill; It would be appropriate to define mathematics as an art of thinking. These basic elements have gradually diversified and progressed with the tendency of the mind to develop them, the desire to know and understand, the development of life in a way that will increase the use of mathematical knowledge and skills, and the increasing relations of other branches of science and art with mathematics.
The relationship between mathematics and life is quite extensive and generally covers the topics of "mathematical order in nature", "real life problems", "use of mathematics in science and art". The use of mathematics in the sciences covers a large part of the existing mathematical knowledge and the fields in which it is used are also quite extensive. The topics covered in the book are as follows: Golden Ratio (in face, body and dental aesthetics; heart, brain, lungs, gynecology, genetics, walking, finance, marketing, physics, architecture, music and painting), Polyhedrons (applications in different branches of science and art) ), Fibonacci Numbers and their uses, Spirals and Spirals in Nature, Mathematical Order in Plants, Music and Mathematics, Fractals and their Applications in Life (economics, music, genetic music, modeling natural forms, medicine, architecture, urban planning, geology, classification of fingerprints, Classification of trees, graphic design, fractal antenna, photo compression, sculpture and painting) and examples of Mathematical Modeling at the point of solving real life problems. In summary; In this book, the mathematical order of nature and the golden ratio, Fibonacci numbers, fractals and regular polyhedra, which have an important place in nature, life, art, aesthetics and some scientific fields, are emphasized.
Azer Arastunoğlu Kasımzade In this book, very important fundamental issues of Differential Equations that can be included in the seminar topics of universities are discussed in order to prepare undergraduate and graduate students. Since DD solutions of Differential Equations can seldom be expressed with implicit formulas, numerical computational methods have been needed over time to approximate their solutions. For this reason, attention has been paid to give the examination properties of DD with the developed numerical solution Finite Element Method (SEM). More than 99% of today's software has been built on the basis of these methods, allowing for high-precision full-scale simulation of engineering structures. In the presented study, the traditional solution methods of Differential Equations are presented in summary form, and their applications are given in parallel with MATLAB tools. Afterwards, the features of using databases in MATLAB are explained and various applications are shown with MATLAB tools, since the analysis of Differential Equations with no implicit solution by SEM requires an extraordinarily large volume of data. For each section, education and training analysis software in MATLAB environment and video presentations of examples are presented in DVD-QR code. This book is of interest to a wide range of professionals, including students, designers, and researchers in the field of Solid Mechanics, Structural Mechanics, adding new color to their education in Differential Equation research.
