Depends what you want to do with them!  Their interesting properties  
come from calculus.

They are generated by simple recurrence relations

     T_0(x) = 1
     T_1(x) = x
     T_{n+1}(x) = 2xT_n(x) - T_{n-1}(x)

or the more complex

T_n(x)=cos(n arccos(x))

but what makes them interesting is
a) they are orthoginal (weight sqrt{1-x^2} )
b) they are useful in approximating other functions.
c) etc

The wikipedia page is rather long and too complicated I guess.

If you are starting to get maths for audio really you should start  
with the complex numbers.
