Given the graph of an ellipse, find its equation, and vice versa. LaTeX example: How … Let's see an example of the inline mode: In physics, the mass-energy equivalence is stated by the equation $E = mc^ 2$, discovered in 1905 by Albert Einstein. For an example right here on Math SE, consider this post, and see how illustrative it is to use actual terms and dots for the examples, ... For example, if you use an ellipsis you may annoy someone but another person may look favourable on your choice, while not using one may produce the polar opposite effect. In which case, all of a sudden b would be the semi-major axis, because b would be greater than a.
