GraphFunction Class

This class creates new graph function by Formula,
and then you can get Points

    public class GraphFunction
    {
        public string Formula { get; init; }
        public Vector2[] Points { get; init; }
    }

formula syntax :

    sum : +, substraction : -, multiplying : *, dividing : /, raise in power : ^ , sqrt : sqrt(number), sin : sin(number),  
    , asin : asin(number), , cos : cos(number), , acos : acos(number), cot : cot(number), tan : tan(number), atan : atan(number)  
    , acot : acot(number), sec : sec(number)

GraphFunction GetPoints

Returns the points of formula from minX to maxX , amount is freq, xSymbol that is symbol that displays x

        protected Vector2[] GetPoints(float minX, float maxX, int freq, char xSymbol = 'x')
        {
            if (string.IsNullOrEmpty(Formula) || maxX == minX) return [new Vector2()];
            if (maxX < minX) throw new ArgumentException("Max cannot be less then min");

            Vector2[] points = new Vector2[freq];
            double currentX = minX;
            CalculationEngine engine = new();

            for (int i = 0; i < freq; i++)
            {
                points[i] = GetPoint(engine, xSymbol, currentX);
                currentX += (maxX - minX) / (freq-1);
            }

            return points;
        }

Usage example:

    GraphFunction parabola = new GraphFunction("x^2" , 10, -10 ,10);
    foreach(var point in parabola.Points)
    {
        Console.WriteLine(point); we get 10 points of parabola
    }

LinearGraphFunction class

linear graph functions, has only two points and that's enough two build graph,

    public class LinearGraphFunction : GraphFunction

LinearGraphFunction GetPoints

        private Vector2[] GetPoints(float minX, float maxX,  char xSymbol)
        {
            if (string.IsNullOrEmpty(Formula) || maxX == minX) return [new Vector2()];
            if (maxX < minX) throw new ArgumentException("Max cannot be less then min");
            CalculationEngine engine = new();
            return [GetPoint(engine, xSymbol, minX), GetPoint(engine, xSymbol, maxX)];
        }

usage:

    var LinearGraphFunction linear = new LinearGraphFunction("-2 * x", -10 , 15);
    foreach(var point in linear.Points)
        Console.WriteLine(point);
    // we get {-10, 20}, {15, -30}
