Are there specific PHP functions or libraries that can help with mathematical calculations, such as those related to the Einheitskreis?

When working with mathematical calculations related to the Einheitskreis (Unit Circle), it can be helpful to use PHP's built-in math functions and libraries to perform calculations such as trigonometric functions (sine, cosine, tangent) and conversions between radians and degrees. The PHP math functions like sin(), cos(), tan(), deg2rad(), and rad2deg() can be used to work with angles and values related to the Einheitskreis. 

// Example PHP code snippet to calculate sine and cosine values for angles in radians on the Einheitskreis
$angle = deg2rad(30); // Convert angle from degrees to radians
$sineValue = sin($angle); // Calculate sine value for the angle
$cosineValue = cos($angle); // Calculate cosine value for the angle

echo "Sine value for angle 30 degrees: " . $sineValue . "\n";
echo "Cosine value for angle 30 degrees: " . $cosineValue . "\n";
