Euclid比赛规则
1. 比赛时长共2.5个小时,150分钟
2. Euclid共有10道题,无选择题,均为简答题,每题都有2-3小题
3. 一些题目只需写出最后的答案,一些题目需要写出计算过程,一些题目需要写出完整证明过程。评分标准不光是以最终结果正确与否给分,也会根据答题步骤及思路和技巧来给分。如果答题步骤或方式过为散乱,即使最终结果是正确的也不会给予满分。
4. 可使用计算器,且大部分计算器均可使用,但还有以下功能的除外
(网络功能,与其他设备沟通功能,存储功能,电脑代数系统,动态几何软件)
University of Waterloo滑铁卢大学官方建议为:
1. Grade 12 open courseware:
这是一个Center for Education in Mathematics and Computing(CEMC)开设的网课,有数学和计算机的课程。滑铁卢大学推荐参赛者上Advanced Functions and Pre-Calculus(高端方程与预备微积分)和Calculus and Vectors(微积分与向量)两门课程
2. Mathematics Resource Manual for High School Students and Undergraduate Studies:
这本书盘点了高中数学的主要内容,不仅能成为准备学术活动的利器,也能帮助同学们由高中更好地进入大学数学的学习
3. Euclid eWorkshop:
这是CEMC为Euclid打造的准备材料,类似于一个带有例题的概念表,盘点了参加Euclid Contest所需要的知识点
4. 往届比赛题目:
往届比赛题目是很珍贵的准备学术活动的资源,做这些题目不仅能帮助参赛者复习知识点,也能让他们更加熟悉Euclid的出题方式和套路,更好地应对比赛
