Greetings
I'm trying to determine the equation of an ellipse with center in one focis, and the major axis with an inclination.
The equation of a ellipse centered in the focis is given, I believe, by:
(x-c)2/a2 + y2/b2 = 1 where the focis coordinates are (c,0)
So
y2 = 1 - (x-c)2/a2
but supose the major axis is inclined by 30 degrees, and the center is all ways the focis? Y2 will be equal to what?
Rotating coordinates is easy. Still, I'm not sure of the final equation solved to y.
Thanks in advance.
Kind regards
