[sdiy] SDIY MATH GOALS--need real help!

[Dan Snazelle]

thanks guys for all the super advice.

I think now that I have a better idea of what i need to learn, i just need to go find some good books on the subjects. This seems to be harder than it sounds though, with so many math textbooks out there and so many of them getting bad reviews.

If anyone here has a good recommendation for an Algebra or Trig book, I would appreciate it.


Thanks a lot!!
