برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
abstract in this thesis at first we comput the determinant of hankel matrix with enteries a_k (x)=?_(m=0)^k??((2k+2-m)¦(k-m)) x^m ? by using a new operator, ? and by writing and solving differential equation of order two at points x=2 and x=-2 . also we show that this determinant under k-binomial transformation is invariant.

Developing problem-solving abilities is a major objective of learning mathematics at school. However, learners’ are still critical. The main purpose this study was to investigate how the problem-based model could enhance in mathematics. used quasi-experimental research with one group pre-test-post-test design. population consisted fifty-four grade eleven learners (aged between 16 19 years old) ...
teacher autonomy is viewed very differently: one teacher may view autonomy as a means to gain substantial freedom from interference or supervision; another may view it as the freedom to develop collegial relationships and accomplish tasks that extend beyond the classroom; and even some others may perceive it as a means for principals to avoid their duties (frase and sorenson, 1992). although th...
