Provide a short quickstart that helps first-time users open and begin using the emulator. Include:

How to open the calculator (on-page widget or fullscreen).
Basic navigation: using the on-screen keypad vs. keyboard input.
Saving or copying results: copy-paste instructions and screenshot tips.

Using the Keyboard

Summarize the most-used keys and shortcuts. Example sections to include on the page:

Power (On/Off)
Numeric keys and decimal
Arithmetic operators (+, -, ×, ÷)
Function keys (sin, cos, tan, log, ln, ^)
Graphing keys (Y=, GRAPH, TRACE, ZOOM)
2nd / Shift functionality description

Display & Modes

Explain display settings and common modes that affect calculations and graphs. Items to document:

Degree vs Radian mode
Float vs Fixed decimal display format
Graphing window settings (Xmin, Xmax, Ymin, Ymax)
Stat/Matrix modes

Graphing Functions

Provide a quick tutorial for graphing, including examples:

Example: To plot y = sin(x):
1. Enter sin(x) into Y1
2. Press GRAPH
3. Use ZOOM to adjust view
4. Use TRACE to inspect points

Also include tips for implicit and parametric graphs if supported by your emulator.

Algebra & Equations

Entering data into a list
Running linear regression and reading the output
Matrix multiplication and inversion

Error Conditions & Troubleshooting

List common error messages users may encounter and concise fixes. Example entries:

Error	Meaning	Fix
ERR:SYNTAX	Expression not formatted correctly	Check parentheses and operators; re-enter expression.
ERR:DOMAIN	Function undefined for input (e.g., log(-1))	Check domain or use complex mode if supported.
ERR:DIVIDE	Division by zero	Adjust equation to avoid dividing by zero.

FAQ & Exam Rules

Quick FAQ and a prominent note about exam use: online emulators are typically not allowed in proctored exams — always check exam rules.
