OpenStudy (misty1212):
its gotta be one of the first ones, a "greater than" since it is the stuff to the right
OpenStudy (misty1212):
it is hard for me to see if that little circle is filled in or is open
OpenStudy (sissyedgar):
o, ok.. makes since. thx
OpenStudy (misty1212):
if it is filled in, use \(\geq\) and if it is open use \(>\)
