Making pi over 6 times a variable?

Hi all. I'm completely new to this and just spent 10 minutes trying ot get this down but can't. Hahaha.

The equation I am trying to write out is y = -5cos(pi over 6 times t).... But I can't get that to work out. The 1st 4 tries just made all my words I used from the tutorials come out in italics and the following 5 tries or so made a LaTex error message....

Please help me figure this out. I think it's an AMAZING concept and would really LOVE to learn it...

Click the equation:

$\displaystyle y = -5\cos{\left(\frac{\pi t}{6}\right)}$.

Thank you very much for the quick response! I greatly appreciate it. I'm trying my best on this... XP
