title: How to find the point on ellipse given the angle
body: <p>I have a ellipse with center point is at origin(0,0) </p>
  
  <pre><code>double dHalfwidthEllipse = 10; 
  double dHalfheightEllipse = 20;
  double dAngle = 30;//Its in degree
  PointF ptfPoint = new PointF();//To be found
  PointF ptfOrigin = new PointF(0, 0);//Origin
  </code></pre>
  
  <p>Angle of point with respect to origin = 30 degree;
  How to get the point now given the above values using C#?</p>
