So would the equation be
?
I'm still kinda confused on the drawing:
[*]How did you figure the distance of the blue line?
.......
[*]If the diameter of the earth is 8000, then the radius should be 4000, why is there a 4100?
.......That's the distance from the center of the Earth to the satellite at it's minimum height. .......
[*]And what is with the 50, 8300, and 4150?
.......The diameter of Earth + maximum height + minimum height ist the complete major axis of the ellipse. 8000+200+100 = 2a.
a = 4150
Since the center of the Earth is a focus the excentricity of the ellipse is 4150 - 4100 = 50
.......
As you may know the ellipse has the property:
I have drawn the minor semi-axis in blue. The slanted line has the length a.
