I have always had trouble with integrals, and I would LOVE to be able to throw a ton at some type of solver such as the one calc101.com has that show me HOW they do the solving so I can learn.

I know matlab and maple both are programs that solve math problems, and I own both. The problem is they don't show step by step solving. Or at least I don't know how to do so in them.

lim as x goes to 4 of (4 - x) / (square root of x - 2)

lim as x goes to zero of (x - tan x) / (x - sin x)

lim as x goes to zero of (1 - cos^2 (2x) ) / x^2

if you could explain any of these it would be so great!!! thank you so much in advance.
