The adomian decomposition method (ADM) was used to solve various wave equations. We compared the obtained solution by ADM with the Reduced Differential Transform Method (RDTM) and the Variational Iteration Method (VIM). The results show that ADM is very effective, simple and easy compared with other methods.

نقوم في هذه الدراسة باستعراض لموضوع الكسور التسلسلية وبعض المفاهيم المهمة ذات العلاقة بالموضوع؛ ثم نعرج بعد ذلك إلى موضوع حساب الكسور التسلسلية وإلى بعض أنواع المتسلسلات المستخدمة في كتابة الكسور التسلسلية. بعدئذ نقوم بإيجاد واستخراج الجذور بإستخدام الكسور التسلسلية، حيث نبدأ بالجذر التربيعي فالجذر النوني ومن ثم الكميات على الصورة . نقوم بعد ذلك بحل المعادلات من الدرجة الثانية بإستخدام الكسور التسلسلية. يلي ذلك استعراض بعض التطبيقات على الكسور التسلسلية في الفيزياء والمعادلات وبعض التطبيقات الأخرى. في ختام الرسالة نعطي حسابات عددية ذات علاقة بموضوع الكسور التسلسلية مع إجراء مقارنة بنتائج يتم التوصل اليها بطرق أخرى. Abstract Though the subject of continued fractions is old; but it is still important and interesting .Accordingly this work come into light. First. We give same important definitions and concepts; then we proceed various to give variation representations using continued fractions such as Fibonacci series. The computation of roots of various kinds is another subject tackled in this concern and the solution of algebraic equations of the second degree using continued fractions, is also presented and discussed . Other important applications of continued fraction are presented, such as their use in physics, in th solution of Schrodinger equations , and in differential equation , to solve for Hermite , Laguerre and Legendre polynomials . Finally, some computations regarding the extraction of roots of real numbers are performed and compared with exact methods. It is also to be stressed that though the subject of continued fraction is an old one, but it is still vital and of interest as a useful topic of research.

Abstract In this thesis, we study different numerical methods used to solve ordinary differential equations of the first and second orders and where related important definitions are given . We will concentrate first on Differential Equations of the first order and the truncation errors which are derived for various methods and those compared with the expected errors , whenever possible . Two applications were given in science of biology and physics which were studied in details . Finally we draw our attention to ordinary differential equations of the second order where we study initial-value problems and boundary-value problems with the application of the wellknown numerical procedures :the shooting method and the finite difference method . The important conclusion we came up with is that the truncation error is always greater than the expected error for all methods used, and this which was expected .
