    If anyone can help it would be appreciated. I have been trying to display an equation with Tex with no luck. I have refreshed the page and still get nothing. Do I have to create the thread to actually see if the equation is correctly expressed?

    In my experience, the Tex equations do not display correctly in the "preview" pane, but they do display correctly after they have been posted to a thread. You can use this thread to check your Tex equations for errors, before posting or creating a whole new thread. Sorry, but this forum software still has some bugs in it.

    \( \Large \frac{1}{1-\frac{v^2}{c^2}} \)

    Thanks for your help Neddy Bate. I see that you have to post to see the equation displayed. The preview does not display the equation.

    \(\sqrt{ab}\)

    \(c_a^b\sqrt[n]{ab}\)
