一般地，把三角形的三个角A，B，C和它们的对边a，b，c叫做三角形的元素。已知三角形的几个元素求其他元素的过程叫做解三角形。解三角形，常用到正弦定理和余弦定理和面积公式等。正弦定理a/sinA=b/sinB=c/sinC=2R（2R在同一个三角形中是恒(The Triangle software, wrote)

Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.
