That makes sense. Before this moment I never thought you were gone. But maybe the fact is that you have gone for so long. Sorry for all the scratches we gave to each other. I thought we would be together eventually one day. Therefore I told myself, as long as my ending would be you, all the stuffers would be worth to bear. Nevertheless, that was obviously my misunderstanding. We lost each other again for this life. I only hope there will be a multi universe among the millions, we could end up with together, for this life.

#新加坡数学# 新加坡的学制是6+4+2，小学六年，中学四年，初院Junior College两年，初院阶段相当于国内的高中。那初院的数学题长什么样？今天给大家看看新加坡南洋初院的2018年的一道考试题。

我们现在不是也在提倡让试题情景化、实用化和趣味化嘛，这道考题也挺有意思的，把纸折起来。英文原题如下，问题在附图中。

A triangle is cut out from a rectangular piece of paper measuring 10 cm by 6 cm using the scissors. To form this triangle, the right-hand corner is folded over so as to reach the left-most edge of the paper, forming a crease for the scissors to cut along, as shown in the diagram below. Let the length of the crease be L cm, the base of the triangle to be folded be x cm and the height of the triangle be y cm.

中文题意是：使用剪刀从 10 厘米 x 6 厘米的矩形纸上剪下一个三角形。 为了剪这个三角形，将右手侧的一角折叠起来对到纸的最左边，形成一个折痕，如下图所示。 设折痕的长度为 L cm，折叠的三角形的底边为 x cm，三角形的高度为 y cm。问题1，证明等式成立(等式看附图)，问题2，使用微分，找到所得折痕的最小长度。
