web solution is you have web access on your phone.
I have a Samsung S3 smartphone.
One of the apps that comes pre-installed with the phone is a calculator.
It has a "basic" option and a "scientific" option, which provides functions for calculating cosine, sine, tangent, etc., but I haven't been able to figure out how to do the inverses: arcsin, arccos, arctan.
Anybody here know how to access these inverse functions? Or does the app, indeed, not provide this functionality?
Alternately, can anybody here recommend an android app for downloading that provides scientific calculator functionality? I will be doing some searches myself, but would still like to hear any personal recommendations, suggestions, experiences, etc. regarding what is out there.
