If you have one, you are either running a very old firmware version, or it's an artifact left over after upgrading your firmware. It's a ghost app, haunting your Prime. Ignore it; it's not supported any more. To exorcise it, upgrade your firmware and/or clear your Prime's memory and start fresh.


Correct. After selecting "Trigonometric", press the Plot key to see the Explorer / Trig in Plot view... as explained in the User Guide.

All of my Primes (HW A, two HW C (old and new keyboard) and D) had Trig Explorer 2 and 3 on them. I deleted all of them. Am I the only one who ended up with multiple Explorers?

Yes, yes you are--- ;-)
