Does this calculator support Degree and Radian modes?

Yes. You can toggle between Degrees (DEG) and Radians (RAD) for all trigonometric operations (sin, cos, tan, etc.).

How do I plot functions on the graph?

Type an expression in terms of 'x' (for example: Math.sin(x), x*x, or Math.cos(x)) in the graph configuration panel and click Plot to render it instantly on the canvas graph.

Can I use my physical keyboard to type equations?

Yes. Standard keys (numbers 0-9, decimal point, operators +, -, *, /, parenthesis, and Enter for equals) are fully mapped to the interface.

How does the calculator handle invalid syntax?

If an expression contains unmatched brackets, syntax errors, or division by zero, the LED glass screen displays a friendly 'Syntax Error' alert.

Frequently Asked Questions

What is the difference between DEG and RAD modes? +

DEG (Degrees) treats circle angles as 360 units, while RAD (Radians) defines circles by 2π units. Toggle DEG or RAD to verify correct trigonometric properties.

How do I type exponents? +

Click the `x^y` key. This inserts the exponent operator symbol `^`. You can type your base, click `x^y`, and enter your power. In the JavaScript parser, this converts to `Math.pow(base, exponent)`.

What values can I plot on the graph canvas? +

Any mathematical equation using variable `x`. Remember to write valid JS math expressions, such as `Math.sin(x)`, `x*x`, `Math.sqrt(Math.abs(x))`, or `Math.sin(x)/x`. The system loops x from -50 to 50 to draw the vector lines.

Does this tool support parenthesis grouping? +

Yes, absolutely. You can nest multiple levels of parenthesis to enforce mathematical order of operations (PEMDAS). Make sure to close all open brackets to avoid syntax errors.
