**Hi all !**

I am a newbie with some quez .. Please help

I have a rather odd problem with my cp 300. I dont know how to type a function as the following : f(x)= 1+arctan(x)-arccos (x)

The problem is that I cant find how to write the -arccos,arcsin,arcsec,arccsc in the manual..I would be greatful if you can help with that ..

I wonder if their is a direct way to write Arctan,SEC,cosec,arcsin,arccos ..etc without rewriting.The hp49g has a special func called trig for those.

Is their something similar to that ???

I mean even hyperbolic trig functions..

ThanX
