Where can I find out what a <> shaped white pill with the number 3 and then a spot to break in half and then the number 9. The other size is designed the same way but it has E on one side before the perforation and what appears to be a 6. Not sure if prescription or over the container, and the tablet is very small and hard to read the numbers. Please Help.

Thanks in advance for anyone's help. I have found some of these in my daughters room, could be a diet pill of some sort, hopefully.
