I copied the whole response and put it into a google doc. I’d be happy to send it to you. Here is the first half to what you claim doesn’t match up: A matrix is a grid of numbers, but the point isn’t the grid. It’s what the grid lets you do. In matrix theory, one of the biggest ideas is that a matrix can store a rule for changing several numbers at once. Imagine a game character is 3 steps right and 2 steps up from the starting point. What if you wanted to stretch the whole map so that every horizontal distance doubles, but vertical distances stay the same? You could store that rule in this matrix: \begin{bmatrix} 2 & 0\\ 0 & 1 \end{bmatrix} The first row tells you how to get the new horizontal position: take 2 times the old horizontal position and 0 times the old vertical position. The second row tells you how to get the new vertical position: take 0 times the old horizontal position and 1 time the old vertical position. So (3, 2) becomes (6, 2). That’s what matrix multiplication is doing here: applying the rule. And you can reuse that same matrix on every point on the map. The other big use you’ll see in class is solving several equations together. A matrix lets you pull out the numbers in front of the variables and organize them so you can work through the equations without rewriting all the x’s and y’s every time. That’s where row reduction comes in. If you remember one thing going back into class: when a matrix acts on a set of numbers, each row is a recipe for one output. That makes the rows and columns feel a lot less arbitrary. 🔢子”だった。凄い。 中国語で2つ目の回答をもう一度言ってください。 大変申し訳ございません。最初の翻訳は「你好，欢迎！(Nǐ hǎo, huānyíng!)」でしたが、2つ目の翻訳は「你好，欢迎你！(Nǐ hǎo, huānyíng nǐ!)」です。これがよりフレンドリーな印象です。次回からは、回答の正確さに気をつけます。お許しください。 うん、話を聞いてた。2つ目の言葉でOKと思った。2つ目の言葉をいいと思いました。答えてください。2つ目の言葉を中国語でもう一度言ってください。 はい、もちろんです
