My Website - Calculus and DE tutorials

  1. Oct 3, 2005 #1
    Hey guys, I just made a website and I included a mathematics tutorial section. The topics range from calc 1 - 3 (the basics). Some of the stuff at this point might be much to easy for you guys, but I'll be adding much harder calculus tutorials and DE tutorials as well. Just gotta start at the beginning before I pile on the hard stuff :)

    Nice site. I'd just like to correct something under vectors though. The projection of b onto a should actually be:

    [tex]\text{proj}_{\vec{a}}\vec{b}=\frac{\vec{a}\cdot\vec{b}}{\mathbf{\vec{a}\cdot\vec{a}}}\,\vec{a}[/tex]

    I think you only had |a| in the denominator.

    thanks! you are correct, i meant to put |a|^2 in the denominator, since a dot a = |a|^2.

    thanks again, ill update it right now.
