Limits of Trig Functions
1. lim sec x - 1 / xsecx (x--->0)
2. lim (1-cosx)^2 / x (x--->0)
3. lim 5x / sin 4x (x--->0)
Sometimes I get these, and sometimes I don't. Is there any specific way I'm supposed to look at these trig. functions? I keep getting marked off for the way I've been solving them. =/
Any help is greatly appreciated! :)
The last one, I know I have to use sin x/x = 1, but every time I use that to justify my answer...I get marked off. ...

That's exactly what I did on my last quiz and she still marked me off. Hmmm. I think I'll just ask her exactly what she wants from me, heh.
Thanks a ton! :D
