How would I find the eccentricity of the ellipse:

x^2/49 + y^2/64 = 1

x^2/49 + y^2/64 = 1

Another constant c is defined as: [itex]c^2 \equiv a^2 - b^2[/itex]

Finally, we define the eccentricity as: [itex]e = \frac{c}{a}[/itex]

If your textbook does not have such a formula or you do not have a textbook (not a good idea!) you could go to "google.com" and enter "ellipse eccentricity". I just did that and found a very simple formula at the first hit.
