近年来,我們中国科学院数学研究所收到了不少关于三分角問題的来信。在这些信中,絕大多数都是来自全国各地的青年学生,他們在钻研数學問題上,敢于通过自己的独立钻研,想尽种种方法来謀求“問題”的解决,这种精神是好的。但是由于对三分角問題的实质缺乏全面的了解,对用圓規直尺三等分任意一角的不可能性沒有得到正确的理解。因此他們白白地耗費了很多时間和精力。根据这种情况,我們认为有必要向青年学生再作一次广泛的說明,使对三分角問題的提法上有較为正
In recent years, the Institute of Mathematics of the Chinese Academy of Sciences has received a lot of letters on the issue of the trigonometry angle. The vast majority of these letters are from young students across the country. They are daring to go through their own independent study in the study of mathematics and try every means to solve the “problems”. This spirit is good. . However, due to the lack of a comprehensive understanding of the essence of the trigonometric angle problem, the impossibility of using the compass ruler to trivialize any of the three corners is not properly understood. So they spent a lot of time and energy in vain. Based on this situation, we think it is necessary to give a more extensive explanation to the young students and make the formulation of the trigonometric angle more positive.
