Answer
Prashant

To see the math and trig functions available----- with excel open click on the function key, in the insert function box/select a category/ select math and trig.  All of the math and trig functions will be listed.

I have not used  graph or charting abilities of excel on a smart phone, so I have no knowledge relative to your question, but I would be surprised if the aps did not exist.

Hope this helps a bit
