  • finite neutrosophic Complex Numbers
    arXiv: General Mathematics, 2011
    Co-Authors: W Vasantha B Kandasamy, Florentin Smarandache
    Abstract:

    In this book for the first time the authors introduce the notion of real neutrosophic Complex Numbers. Further the new notion of finite Complex modulo integers is defined. For every $C(Z_n)$ the Complex modulo integer $i_F$ is such that $2F_i = n - 1$. Several algebraic structures on $C(Z_n)$ are introduced and studied. Further the notion of Complex neutrosophic modulo integers is introduced. Vector spaces and linear algebras are constructed using these neutrosophic Complex modulo integers.

  • Complex Numbers and Geometry
    Complex Numbers from A to ... Z, 2014
    Co-Authors: Titu Andreescu, Dorin Andrica
    Abstract:

    This chapter is dealing with the first connections between Complex Numbers and geometry and it is organized into six sections containing a rich material involving the following aspects: simple geometric notions and properties in the language of Complex Numbers, conditions for collinearity, orthogonality and concyclicity in terms of Complex Numbers, similar triangles, equilateral triangles, elements of analytic geometry in the Complex plane, the study of circles. The theoretical material is illustrated by suggestive examples and problems of various level of difficulty.

  • Complex Numbers from A to ... Z
    2014
    Co-Authors: Titu Andreescu, Dorin Andrica
    Abstract:

    It is impossible to imagine modern mathematics without Complex Numbers. The second edition of Complex Numbers from A to … Z introduces the reader to this fascinating subject that, from the time of L. Euler, has become one of the most utilized ideas in mathematics. The exposition concentrates on key concepts and then elementary results concerning these Numbers. The reader learns how Complex Numbers can be used to solve algebraic equations and to understand the geometric interpretation of Complex Numbers and the operations involving them. The theoretical parts of the book are augmented with rich exercises and problems at various levels of difficulty. Many new problems and solutions have been added in this second edition. A special feature of the book is the last chapter, a selection of outstanding Olympiad and other important mathematical contest problems solved by employing the methods already presented. The book reflects the unique experience of the authors. It distills a vast mathematical literature, most of which is unknown to the western public, and captures the essence of an abundant problem culture. The target audience includes undergraduates, high school students and their teachers, mathematical contestants (such as those training for Olympiads or the W. L. Putnam Mathematical Competition) and their coaches, as well as anyone interested in essential mathematics

  • Secondary teachers’ conception of various forms of Complex Numbers
    Journal of Mathematics Teacher Education, 2015
    Co-Authors: Gulden Karakok, Hortensia Soto-johnson, Stephenie Anderson Dyben
    Abstract:

    This study explores in-service high school mathematics teachers’ conception of various forms of Complex Numbers and ways in which they transition between different representations of these forms. One 90-min interview was conducted with three high school mathematics teachers after they completed three professional development sessions, each 4 h, on Complex Numbers. Results indicate that, in general, these teachers did not necessarily have a dual conception of Complex Numbers. However, they demonstrated varying conceptions with different forms of Complex Numbers. Teachers worked at an operational level with the exponential form of Complex Numbers, but there was no evidence to indicate that they had a structural conception of this form. On the other hand, two teachers were very comfortable with the Cartesian form and exhibited a process/object duality by translating between different representations of this form. These results indicate that high school teachers need more opportunities to help them develop a dual conception of each form ( multiple duals ), which in turn can result in developing a dual conception of Complex Numbers. An interesting phenomenon that we found was that teachers who taught courses such as geometry and international baccalaureate were able to draw from their teaching experiences as they attempted the interview tasks. This particular observation may suggest that teachers’ teaching assignments coupled with appropriate professional development activities could facilitate their understanding of these concepts.

  • The Inner Product and Conjugate of Finite Sequences of Complex Numbers
    2005
    Co-Authors: Wenpai Chang, Hiroshi Yamazaki, Yatsuka Nakamura
    Abstract:

    Summary. The concept of “the inner product and conjugate of finite sequences of Complex Numbers” is defined here. Addition, subtraction, scalar multiplication and inner product are introduced using correspondent definitions of “conjugate of finite sequences of field”. Many equations for such operations consist like a case of “conjugate of finite sequences of field”. Some operations on the set of n-tuples of Complex Numbers are introduced as well. Additionally, difference of such n-tuples, complement of a n-tuple and multiplication of these are defined in terms of Complex Numbers.

  • The Inner Product and Conjugate of Matrix of Complex Numbers

    Co-Authors: Wenpai Chang, Hiroshi Yamazaki, Yatsuka Nakamura
    Abstract:

    Concepts of the inner product and conjugate of matrix of Complex Numbers are defined here. Operations such as addition, subtraction, scalar multiplication and inner product are introduced using correspondent definitions of the conjugate of a matrix of a Complex field. Many equations for such operations consist like a case of the conjugate of matrix of a field and some operations on the set of sum of Complex Numbers are introduced.
