I don't have my manual with me right now, I am at work and it is at home. Does anyone use this calc here? I am trying to figure out how to do degree, minute, second calcs with the 48. I use the casio FX300 which has that function on the front keys but is not as accurate as the 48 which has more extended digits to work with. I am calculating tangents of very tiny angles, 0.01 arc seconds and less and am running out of accuracy on the casio but can't remember right now how to do it on the 48, specifically, 90 degrees minus 0 Degrees, 0 minutes, 0.01 arc seconds. On the casio, it returns you a number in degrees and if you hit the degree button again, converts it to decimal format which is what I need. Anyone remember how to do that on the HP48G?

Never mind, I found a site to download the manual, in the comp at work, found the right page.

I have no idea if this will help but if you type "tan 0.01 arc seconds" into google it gives you an answer.
