Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

打造你的超級大腦：Gemini 與 NotebookLM 的雙效知識管理術
想要打造專屬的超級大腦嗎？這部影片將教你如何完美結合 Gemini 與 NotebookLM，透過 AI 雙向同步技術徹底革新你的知識管理流程。在資訊爆炸的時代，特教老師與教育工作者常面臨資料超載的困擾，我們將手把手示範如何將海量文獻轉化為精確的行動指南。從資料收集、重點消化到最終報告生成，這套高效協作流程能確保內容兼具創意發想與事實精準度，大幅提升你的研究與備課效率。

💡 常見問題 (FAQ)
Q：Gemini 與 NotebookLM 在知識管理中的角色分工有何不同？
Gemini 定位為「創意工作台」，擅長邏輯推理、專案規劃與跨領域的創意生成；NotebookLM 則是「資料分析室」，專注於處理使用者上傳的特定文件，其核心優勢在於精確提取重點、整理脈絡，並嚴格標示資訊的引用來源，確保內容 100% 來自原始資料。

Q：如何確保 Gemini 生成的報告內容具備事實根據？
最佳實作路徑是先將資料同步至 NotebookLM 進行「消化」，利用其事實查核功能產生精確摘要與比較表，再將這些經由 NotebookLM 整理後的精華內容帶回 Gemini 進行最終的文案潤飾與格式生成。這種「進去、處理、再出來」的流程能有效避免 AI 產生幻覺。

Q：在使用 AI 雙向同步功能時，有哪些必須注意的限制？
首先，部分新功能採分批開放，若帳號尚未出現選項請耐心等待；其次，若遇同步延遲，請直接「重新整理網頁」即可解決多數問題；最後必須警惕，刪除 NotebookLM 內的筆記本屬於永久性操作，兩端內容會同時移除且無法復原。

Algebra II on Khan Academy: Your studies in algebra 1 have built a solid foundation from which you can explore linear equations, inequalities, and functions. In algebra 2 we build upon that foundation and not only extend our knowledge of algebra 1, but slowly become capable of tackling the BIG questions of the universe. We'll again touch on systems of equations, inequalities, and functions...but we'll also address exponential and logarithmic functions, logarithms, imaginary and complex numbers, conic sections, and matrices. Don't let these big words intimidate you. We're on this journey with you!

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.

The distinctive feature of the Italian Army in World War Two was its poor and insufficient armament.
Even though weapons produced at the famous Italian arms factory Beretta were of the highest quality, the rest were known for their very low quality or obsolete nature.
