AI Thread Summary
The discussion centers around issues with LaTeX formatting in a post. The user is experiencing frustration with equations not displaying correctly, specifically with the notation for "v dot v" not rendering properly and multiple instances of the same equation appearing. A known bug causing old images to show up in previews is mentioned, with a suggested workaround to refresh and resend after each preview to avoid duplication. The equations in question include kinetic energy formulas, highlighting common LaTeX challenges faced by users.

I'm trying to make a post, but the latex is frustrating me. I typed in the following two lines.

[t*x]KE=\frac{1}{2}mv^2[/t*x]

[t*x]=\frac{1}{2}mv\cdot v[/t*x]


It just gives me a v and a dot, intead of v dot v, and it put both equations on one line. I attached an image of what showed up on the 'preview post.' I also had another equation:

[t*x]KE=\frac{1}{2}m(37)[/t*x]

This one was duplicated, so the equation showed up twice, one right below the other.

There's a known bug that makes old images appear in previews. There are many threads about it. The workaround is to refresh and resend after each preview.

KE=\frac{1}{2}mv^2

=\frac{1}{2}mv\cdot v
