hello everyone.

i am considering changing my major from computer sciences to aeronautical engineering. however for a bachelor's degree in aeronautical eng. i am required to have analytic geometry and calc I, II, & III. i'm not so hot in the algebra area, but aeronautics is something that i am really interested it.

i feel that the biggest problem i face is these classes. i feel i can accomplish this, but would like to improve upon what i have already learned. if anyone out there has utilized any online resources for improving their math skills, could they give their thoughts and suggestions?

at one time i found an entire mathematical book that was written by a bunch of authors, and published online, however i cannot find that now.

Thanks!
