What's New in TI-Nspire™ CX Version 4.0?
TI-Nspire™ CX Computer Software
Working with Documents - Zoom to Fit
- Scale the document page to fit the available window size.
Working with Documents - Set default page size
- Set the default page size as either Computer or Handheld for new documents.
Graphs and Geometry - MathDraw
- MathDraw, lets you use touchscreen or mouse gestures to create points, lines, triangles, and other shapes. For example, if you draw an approximately triangular shape, the tool interprets it as a triangle.
Lua Script Editor - Zoom Text
- Adjust the size of the text in your script and in any of the tool panels.
TI-Nspire™ CX Handhelds and Computer Software
Working with Documents - Angle Mode Indicator
- An indicator now shows the angle mode (Degrees, Radians, or Gradians) in effect for the current application. On handhelds, the indicator appears at top of the document screen. In desktop software, the indicator appears in the document status bar.
Graphs - Exact Window Settings
- Use expressions such as 7/3 or 2•π for exact input of custom window settings. The values appear in exact form on the axes and in the Window Settings dialog the next time you display it.
- On TI-Nspire™ CX technology, fractional input is preserved as-is. Other exact inputs, such as radicals, are replaced with the evaluated results.
- On TI-Nspire™ CX CAS technology, fractional and other exact inputs are preserved.
Geometry - Force Triangle Angles to Integers
- Restrict the angles of a triangle to integer values as you create or edit the triangle. This feature restricts the angle sum in a triangle to 180 degrees.
3D Graphing - Orthographic View
- You can customize the 3D environment to show 3D graphs in either Orthographic Projection or Perspective View.
Graphs and Geometry - Automatically Label Points
- Automatically apply labels (A、B、..., Z、A1、B1, and so on) to points, lines, and vertices of geometric shapes as you draw them.
Graphs and Geometry - Directed Angle Measurements
- A measurement tool that lets you create directed angle measurements. You can set clockwise or counterclockwise orientation.
Graphs and Geometry - Bounded Area Selection
- Include the x-axis as a boundary when defining a bounded area.
Graphs, Geometry, and 3D Graphing - Views Preserved
- When you switch among the Graphs, Geometry, and 3D Graphing views, the most recently used window/view settings for the selected view are applied. You can also undo and redo view changes.
Data & Statistics - Display Digits and Diagnostics
- Display Digits setting lets you select the display format for numeric labels in the current document.
- New Diagnostics setting lets you display the value of the r² or R² statistic under certain regression equations.
주의
일단 OS를 업그레이드 하고 나면, 원래대로 다운그레이드 하는 것이 어려울 수 있습니다. 기존 OS에서만 작동하는 조금 덩치 큰 프로그램(예: Ndless)이 있는데, 그런 프로그램을 사용하신다면, OS 업그레이드를 진행하는 것이 유리할지 미리 알아보시는게 좋습니다.

Step 2 (FTC의 마법): 면적의 변화율(미분)은 그 지점의 그래프 높이 f(A)와 같습니다. Step 3 (보정): 다음 A = 현재 A - (면적 오차 / 현재 높이) 공식을 사용하여 A를 이동시킵니다. 결론: 오차를 현재 높이로 나누면, 오차를 메우기 위해 필요한 가로 길이(ΔA)가 나옵니다. 이 과정을 반복하면 정답에 도달합니다! const canvas = document.getElementById('graphCanvas'); const ctx = canvas.getContext('2d'); const iterText = document.getElementById('iterText'); // 수학 설정 const targetArea = 20; const f = (x) => Math.sqrt(x) * 2; // 피적분 함수 f(x) = 2√x const F = (x) => (4/3) * Math.pow(x, 1.5); // 정적분 결과 F(x) = ∫ 2√x dx = 4/3 * x^(3/2) let A = 1.5; // 초기값 let iteration = 0; let animating = false; // 그래프 드로잉 설정 const scale = 50; const offsetX = 60; const offsetY = 380; function drawGrid() { ctx.strokeStyle = '#f1f3f4'; ctx.lineWidth = 1; ctx.beginPath(); for(let i=0; i 2026 04.11 참값 : A = ±2√5 근사값 : A≈±4.472135954999579392818347 2026 04.10 fx-570 ES 입력 결과 초기값 입력 반복 수식 입력 반복 결과 2026 04.10 파이썬 코드 검증 결과 초기값: 5.0 반복 1회차: 4.5000000000 반복 2회차: 4.4722222222 반복 3회차: 4.4721359558 반복 4회차: 4.4721359550 반복 5회차: 4.4721359550 초기값: 10.0 반복 1회차: 6.0000000000 반복 2회차: 4.6666666667 반복 3회차: 4.4761904762 반복 4회차: 4.4721377913 반복 5회차: 4.4721359550 2026 04.10 감사합니다. 주말 잘 보내세요. 2026 03.06
