初中数学开窍指南 掌握解题通法 vs EqualMath

初中生学数学最大的问题是不开窍，思路不对，方法不对。 本应用建议，通过学生自己在解题过程中不断地归纳，再解题，再归纳，掌握解题通法，帮助初中生成为初中数学优等生。 本应用在数学思想方法的基础上，揭示了注重解题过程是解决压轴题的核心，解题过程就是从已知条件到结论的探索和转化，并剖析了六年（2016-2021）上海中考真题中压轴题的解题过程。 本应用介绍了中考数学压轴题中涉及的数学思想方法包括：函数思想, 方程思想, 数形结合思想, 分类讨论思想, 化归和转化思想；以及中考数学压轴题常用解题方法和精选的几何模型。 解几何题，画图可以帮助思考。本应用还提供了动点几何画板，该画图工具支持平移，旋转，翻折，动点等功能，用于观察条件与结论之间的关系。 本应用没有后台服务器手机用户信息。 隐私政策：https://blog.csdn.net/u2kxxy/article/details/124945414 本应用遵循Apple标准许可协议：https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Designed for Apple Pencil and iPad, version 3.1.7 now lets you quickly sketch with basic elements — points, lines, and shapes — to support theoretical exploration. Function graphs are included. Core features are free.But includes some paid features: linked point function, hidden circle and color block function, creating more than 5 folders, radian display in the plane coordinate system, 3D coordinate system, vector arrow, parametric equation, water drop coloring, etc. Beyond geometry, sticky notes are central: pin them to the canvas to highlight key steps, while unwanted ink can be erased to keep your workspace clean. ### Additional Features 1. **Handwritten uppercase letter recognition** – instantly names vertices as you draw geometric figures. Turn it off to use freeform handwriting for names. 2. **Export to Photos** – one-tap export with no watermark. 3. **Import from Photos** – insert an image directly onto the canvas (display only, no recognition). Supports importing PDF files. 4. **Points, lines, and shapes** – select what you need. A key highlight: drag from a vertex of any shape to create a new point – no need to open the menu. 5. **Lasso tool** – select content or activate locked geometry elements. For points, three selection methods are supported: draw a line near the point, draw a line that passes through the point, or draw a small circle around it. 6. **Paint bucket** – fills enclosed geometric figures and regions, dynamically sensing surrounding areas to some extent. 7. **Infinite canvas** – the canvas automatically expands in all directions as you add more ink. 8. **Function graphs** – plot single-variable expressions and parametric equations. 9. **Multi-point linkage** – explore geometric problems involving multiple moving points. 10. **3D coordinate system** – the current release introduces a 3D coordinate space where you can place points and set spatial coordinates. 11. **3D Geometric Shapes: triangular prism, quadrangular prism, cylinder, cone, triangular pyramid, quadrangular pyramid Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
