WPF-라디오 버튼을 클릭 할 때 코사인 함수 플로팅

방금 C #을 배우기 시작했고 사용자가 WPF GUI 인터페이스를 사용하여 라디오 버튼을 누를 때 코사인을 플로팅하고 싶습니다. 다른 클래스에서 호출 객체를 사용하는 방법에 문제가 있다고 생각합니다. 미리 감사드립니다. 아래는 내 코드입니다.

namespace WpfApplication2
{
    using OxyPlot;
    using OxyPlot.Annotations;
    using OxyPlot.Axes;
    using OxyPlot.Series;

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }



        private void button_Click_2(object sender, RoutedEventArgs e)
        {
            if (radioButton1.IsChecked == true)
            {
                MessageBox.Show("Plot Cosine");
                //I think solution should be something like this
                //MainViewModel.MyModel.Series.Add(new FunctionSeries(Math.Cos, -10, 10, 0.01, "cos(x)"));

            }
        }

    }

    public class MainViewModel : Window
    {
        //Plotting without any user input
        public const double Pi = 3.14159265358979323846;
        public const int SpeedOfLight = 3 * 10 ^ 8; // m per sec.


        //OxyPlot.Wpf.PlotModel plot = new OxyPlot.Wpf.PlotView();

        public MainViewModel()
        {
            MyModel = new PlotModel { Title = "Your Equation", LegendTitle = "Equations" };
            MyModel.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom, Title = "Distance" });
            MyModel.Axes.Add(new LinearAxis { Position = AxisPosition.Left, Title = "Height" });


            //Determine your range for the plot
            //MyModel.Axes.Add(new LinearAxis(AxisPosition.Bottom, -10, 10));
            //MyModel.Axes.Add(new LinearAxis(AxisPosition.Left, -5, 5));


            MyModel.Series.Add(new FunctionSeries(Math.Cos, -10, 10, 0.01, "cos(x)"));
            MyModel.Series.Add(new FunctionSeries(Math.Sin, -10, 10, 0.01, "sin(x)"));

            LineSeries linePoints = new LineSeries() { };
            double x, y;
            DataPoint XYpoint = new DataPoint();
            for (x = -10; x <= 10; x += 0.01)
            {
                //Make sure not 1/3 since C# will read it as integer divided by integer hence 1/3=0
                //Use Math.Pow for powers
                //Definately Matlab is easier to plot stuff XD
                y = 1.0 / 2.0 * Math.Pow(x, 2) + 1;
                XYpoint = new DataPoint(x, y);
                linePoints.Points.Add(XYpoint);

            }

            MyModel.Series.Add(linePoints);
            MyModel.InvalidatePlot(true);

        }


        public PlotModel MyModel { get; private set; }

    }

}

다음은 XAML 코드입니다.
