title: finding a point on an ellipse circumference which is inside a rectangle having center point, height and width?
body: <p>I have a rectangle in .NET in which I draw an ellipse.</p>
  
  <p>I know the width, height and center point of that rectangle.</p>
  
  <p>Of course the center point of the rectangle is also the center point of the ellipse.</p>
  
  <p>I know how to calculate a point on a circle, however I have no clue about an ellipse.</p>
  
  <p>I have those parameters and an angle, i need the point on the ellipse, can someone post the formula?</p>
  
  <p>I saw somewhere you need to calculate 2 points in which 2 radii will go, the sum of the radii will be fixed and they will change in size accordingly.</p>
  
  <p>I don't know how to do that, I only have the rectangle height, width and center point and of course the angle I wish to find the point at.</p>
  
  <p>thanks for any help
