2018 年广西桂林电子科技大学数学专业英语考研真题 A 卷注意：答案必须全部写在答题纸上，写在试题上无效；答案要标注题号，答题纸要填写姓名和考号，并标注页码与总页数；交卷时，将答题纸与试题一起装入试卷袋，密封签字。英译汉 1. (1) logical deduction (2) higher algebra (3) rational function (4) three over two (5) initial-value problem (6) the derivative on the left

2.The function f(x) approaches infinity as x tends to zero. 3.No modern scientific and technological branches could be regularly developed without the application of mathematics. 4.In geometry an angle is defined as the set of points determined by two rays having the same endpoint. 5.Numerical partial differential equations is a large area of study. The subject includes components in the areas of applications, mathematics and computers. These three aspects of a problem are strongly tied together that it is virtually impossible to consider one in isolation from the other two. It is impossible (or at least, fool-hardy) to consider the applied aspect of a problem without considering at least some of the mathematical and computing aspects of that problem. Often, the mathematical aspects of numerical partial differential equations can be developed without considering applications or computing, but experience shows that this approach does not generally yield useful results.

6. Often, when numerical techniques are going to be used to solve a physical problem, it is not possible to thoroughly analyze the methods that are used. Any time we use methods that have not been thoroughly analyzed, we must resort to methods that become a part of numerical experimentation. As we shall see, often such experimentation will also become necessary for linear problems. In fact, we often do not even know what to try to prove analytically until we have run a well-designed series of experiments.
