Here are 7 months that you left my son. I write this letter to you in order to know how you go. How does your life occur over there? I learned that your unit returned at the base thanks to information televised… In the last letter that I received from you, you said to me that the combat is very hard and that you would ask whether you had made well be soldier. Last week I received the visit of one of your friends who is in permission, Paul Stewart. We lengthily discussed the life in Iraq, then

Etablir un mécanisme de justice constitutionnelle suppose que le constituant résolve simultanément trois séries de questions. Les premières sont relatives à la composition de cette organisme. Les deuxièmes intéressent le moment où le contrôle de constitutionnalité sera opéré. Le troisième intéresse le déclanchement et els effets du contrôle. S'agissant de la composition de l'instance de contrôle, les appellations de ces instances peuvent avoir une signification, selon que l'on parle de cours ou

. 5) Résolution d'équations solve ou csolve (pour les complexes) en anglais, résol ou résolc en français permet de résoudre des équations, avec la syntaxe solve(f(x)=0,x) ou solve(f(x)=g(x),x). Exemples : solve(x^2-6x-9 = 0,x) donnera x =−3( √ 2 – 1) ou x=3( √ 2+1) . csolve (x^2+1=0,x) donnera x =i or x=−1 (réponse "false" si on utilise ici seulement solve !). La résolution d'équations ne se limite pas aux polynômes ou aux zéros d'une fonction. Exemple : solve(x = ln(3x),x) donnera x =,619061

Babylonians, indicating the techniques they used to solve them. The Egyptian civilisation is a precursor in the mathematical reflexion. The use of this scientific tool was a support to their daily tasks, such as the construction of habitats or the wage distribution. A practical utilization can be seen throughout the range of problems they faced, outlined here below. In both algebra and geometry, the Egyptians have demonstrated very interesting techniques to solve their puzzles. One of the most admirable

Among scientific subjects we have mathematics which sometimes is considered as a very difficult subject by students.

stabilize the government. However, to me the U.S. and UN interventions in Somalia are unlikely to resolve the country's crisis because they do not offer solutions based on African initiatives.  That should not be surprising since outside attempts to solve Africa's problems have regularly proven ineffective and even counterproductive. Indeed, international military approaches have only exacerbated fundamentalism in Somalia. The international community needs to realize that its current and previous policies
