<h1>YonnCalc Documentation</h1>

<h2>General Information</h2>
<p>
    YonnCalc is a desktop application that allows you to perform various calculations and plot graphs of functions.
</p>

<h2>Expression Input</h2>
<p>
    In YonnCalc, you can enter arithmetic expressions in infix notation using the following operators and functions:
</p>
<ul>
    <li>Brackets: ( )</li>
    <li>Addition: +</li>
    <li>Subtraction: -</li>
    <li>Multiplication: *</li>
    <li>Division: /</li>
    <li>Exponentiation: ^</li>
    <li>Modulus: mod</li>
    <li>Unary plus: +a</li>
    <li>Unary minus: -a</li>
    <li>Cosine function: cos(X)</li>
    <li>Sine function: sin(X)</li>
    <li>Tangent function: tan(X)</li>
    <li>Arccosine function: acos(X)</li>
    <li>Arcsine function: asin(X)</li>
    <li>Arctangent function: atan(X)</li>
    <li>Square root function: sqrt(X)</li>
    <li>Natural logarithm function: ln(X)</li>
    <li>Decimal logarithm function: log(X)</li>
</ul>
<p>
    Note that you can use the variable X in expressions to compute functions.
</p>

<p>
    Input can be done by clicking the buttons in the application or by using the keyboard.
</p>

<h2>Expression Evaluation</h2>
<p>
    To evaluate the entered expression, input it completely and press the "=" symbol.
    YonnCalc will perform the calculations and display the result.
</p>

<h2>Function Graphing</h2>
<p>
    In YonnCalc, you can also plot the graph of a function defined by an expression in infix notation with the variable X.
    To plot a graph, you need to specify the domain and range of the function.
    The graph will be displayed with coordinate axes, a scale, and a grid with adaptive spacing.
</p>

<h2>Limitations</h2>
<p>
    When using YonnCalc, please consider the following limitations:
</p>
<ul>
    <li>The domain and range of functions are limited to numbers from -1000000 to 1000000.</li>
    <li>The decimal precision is at least 7 digits after the decimal point.</li>
    <li>The length of the input expression is limited to 255 characters.</li>
    <li>The scale of the graph cannot be changed by the user.</li>
</ul>

<h2>Usage Examples</h2>
<p>
    Here are some example expressions that can be entered into YonnCalc:
</p>
<ul>
    <li>Calculation: (2 + 3) * 4</li>
    <li>Calculation with variable: sin(X) + cos(X)</li>
    <li>Graphing: X^2, domain: [-10, 10], range: [-100, 100]</li>
</ul>
