Pls let me know about the value of e=1/2?

I have to find the vertices, foci, and both axes lengths.  I can do all this but I don't understand what to do with 36x^2 + 25y^2  without affecting the 1 on the right side of the...

I am asked to find the center and intercepts of an ellipse and a hyperbola. also, to give the domain and range of each graph i am given.

the orbit of the earth around the sun is an ellipse  sun  is on one foci. if length of major axis is 300 million km and eccentricity is 0.0167 find minimum and maximum distance...

An ellipse with the equation [((x-1)^2)/9]+[(y^2)/8]=1 Show that the given ellipse in polar co-ordinates has the form a+rcosTheta = br additionally determine the values of a and b...

We know lengths of the two axis, and we know the angle of the line. We can figure out the foci, but I can't see what to do with that information. Hope you can help. Regards.
