I wish that I had paid more attention to math when I was in high school. So many things that I like to do depend on a math background and playing catchup now is a little frustrating. Catch up I must if I wish to pursue my dreams, so I am always on the lookout for good math sites. The best related site that I’ve found so far is Khan Academy. Many of the newer “learn to program” sites share a lot of structure in common with Khan Academy. Right now, I’m studying limits and am about to jump into derivatives. I need to brush up on trigonometry as well, and there is a new article over at better explained that really nails home the commonly used points. Maybe some day soon, I’ll be able to crack those books on Digital Signal Processing and not get a headache when I see the equations.
