please help me Find the center, vertices, foci and endpoints with the minor axis of the ellipse of 2x^2+3y^2=18
~~~~~~~~~~~~~~~~~~~~~~~

2x^2+3y^2 = 18   --->  (divide both sides by 18. You will get)  --->

 = 1  --->

 = 1.


It is the canonical equation of the ellipse with the center at the origin (x,y) = (0,0), 
the major semi-axis a = 3, the minor semi-axis b = .

Vertices are (3,0), (-3,0), (, ),  (,),

The linear eccentricity of the ellipse is the number  =  =  = .

The foci are the points (c,0) = (,) and (-c,0) = (,).




Figure.  The ellipse    = 1.
