0.999…. is equal to 1 or not?
2020-08-31
0.9999……=1? This question shows up every year. It’s a 0.9999……=1 anniversary, right? Today MathPots also want to try to cook this stuff to everyone.

0.999999…..=1? 每年都要辦的0.9bar周年慶！
2020-08-27
0.999999….. = 1? 這個問題幾乎每年都會在民間被拿出來吵一輪，對長期有在數學相關社團或群組的人來說可能已經感到有些厭煩。出現的頻率讓人覺得… 根本是0.9bar周年慶吧 XD 熱潮又漸漸過去，數之釜今天也來挑戰炒冷飯，看是否能炒出老少咸宜的滋味。

In the last meal [calculus]The clarification of ε-δ definition, we knew the actual meaning of $latex \varepsilon -\delta$ definition. This time we are going to use it. In this dish, I will show you the basic problem in $latex \varepsilon -\delta$ definition. Hope to make you understand clearly!

2020-08-24
在上一道菜[微積分]ε-δ定義的觀念釐清中，我們知道到了ε-δ定義的實際意義。知道定義後，這次我們要來實際運用它。在本道菜色中提出了基本題型，希望能讓你們更清楚的瞭解。

或許有人會說，泰勒斯是哪位，我只知道Taylor Swift。但接下來要講的定理你一定有聽過，而且在國中階段初學幾何時一定也用過不少他的發現。

[微積分]ε-δ定義的觀念釐清
2020-08-13
相信大家初次認識微積分時，應該是先學會最簡單的極限概念、微分和積分吧？然而看了微積分相關的書籍才發現怎麼第一章就跑出了奇怪的ε-δ定義，即使背了也只知道大概，沒有相當透徹的理解。本篇的目的便是把和極限相關的概念釐清，也包含ε-δ定義。
