以清华大学为首的“华约”自主招生选拔考试于3月1日进行,和去年一样,今年共考查了7道解答题,其中内容涉及到三角、数列、函数、不等式、解析几何、概率等高中知识,与往年“华约”强调的考点一脉相承.虽然全卷并未出现明显竞赛知识点,但由于整体计算量较大且突出了对数学思维能力的考察,因此具有较好的区分度.下面我们一起来看看这七个问题.1.(10分)在五个正整数中任取四个求和,所有的和构成集合{44,45,46,47},求这五个数.
Tsinghua University, led by Tsinghua University, “Hua Jiao” self-enrollment selection examination conducted on March 1, and last year, this year a total of seven answer questions were examined, which involves the triangle, sequence, function, inequality, analytic geometry, Probability of contour knowledge, with the previous years “Hua Jiao ” emphasizes the test points the same strain.Although the whole volume did not appear obvious contest knowledge points, but because the overall calculation is large and highlights the ability to think of mathematical thinking, it is better Let’s take a look at these seven questions together. (10 points) Take four sums in any of the five positive integers, all of which form {44,45,46,47} These five numbers.
