Good trig books?

I've heard good things about the following:

Trigonometry, Gelfand. I own it, and am in fact looking at it right now. I can guarantee it's a good one. It has creative problems, and many proofs. I highly recommend it.

 

I have a Larson&Hostetler(&Edwards?) Trigonometry book. Much of it is very, very good, but I struggled to understand about vectors, their projections, dot and cross products. I have studied more than once, in fact 3 or 4 times in my life and still not able to understand for more than a few seconds at a time, and just barely. Is this set of topics just difficult, or is this not the best book for this set of topics? Anybody know of a better Trigonometry book which treats these topics more clearly?

 

For basic trig:

symbolipoint, wouldn't a linear algebra book be a better choice for learning vectors, etc.?
