Upgrade to TI-Nspire™ CX technology version 4.2
Get the most out of your TI-Nspire™ CX technology
Powerful new features deliver expanded capabilities for teaching and learning mathematics from middle grades through high school.
The version 4.2 upgrade is available for:
- TI-Nspire™ CX Handheld
- TI-Nspire™ CX CAS Handheld
- TI-Nspire™ CX Student Software
- TI-Nspire™ CX CAS Student Software
- TI-Nspire™ CX Teacher Software
- TI-Nspire™ CX CAS Teacher Software
- TI-Nspire™ CX Navigator™ Software
- TI-Nspire™ Navigator™ NC Software
Using TI-Nspire™ CX technology version 4.2 ensures you have access to the latest features and functionality including the ability to:
Quickly add sliders in Graphs and Notes applications
- Automatically generate sliders when entering parameters for certain functions, equations, or sequences.
- Available in the Graphs and Notes applications.
Graph relations in a familiar form
- Graph relations of the form:
- Equations and inequalities equivalent to y = f(x), such as y = √x
- Equations and inequalities equivalent to x = g(y), such as x-sin(y) ≥ 1⁄2
- Conic equations and inequalities, such as x2 + y2 ≥ 1⁄2 + y
- Graph relations using ≤, <, =, >, and ≥
- Available in ScratchPad, Graphs, and in the Analytic Window of the Geometry application.
Easily access math actions
- Display the available actions for an equation or expression through the context menu.
- Actions might include: Solve Numerically, Try to Factor, and Complete the Square.
- Limited to available functionality in the system and may be restricted in Press-to-Test settings.
- Available in Notes, Scratchpad, and Calculator applications.
Graph relations from the Notes and Calculator applications
- Graph a function or relation directly from its context menu.
- Graph appears on the same page as the selected function or relation, when possible.
- Available for many functions and relations in Notes, Scratchpad, and Calculator applications.
The following features are new in the TI-Nspire™ CX Teacher Software, TI-Nspire™ CX Navigator™ Software, and TI-Nspire™ Navigator™ NC software.
Prepare Class Handhelds Remotely
- Manage the settings of connected handhelds from the teacher’s computer. Handhelds may be connected through wired or wireless connections.
- Use the Prepare Handhelds feature to quickly manage the following on all connected handhelds:
- Clear the Scratchpad
- Apply and save document settings
- Enter and exit Press-to-Test sessions
The following features are new in the TI-Nspire™ CX Navigator™ Software, and TI-Nspire™ Navigator™ NC software.
New View Option for using Capture Class
- Capture handheld screens automatically in 15-second intervals.
- The new default interval for auto refresh for Class Capture is 15 seconds.

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
