This is what the problem really says. I thought by doing that integral was how you did it. Show that for on [-1,1], the expression for aj is given by:

Originally Posted by lacy1104 two more discrepancies here. in the first post you had in the denominator, which made the integral impossible. secondly, now this appears and you never told us anything about it. Please try to describe the problem completely, we do not have your text book

Show that for on [-1,1], the expression for aj is given by: I was wrong in the first entry. it is - T0(x) = 1, T1(x)=x In general, Ti(x)= cos[i arccos x], i > 0 It is posted on this website (its question 3b) http://www.math.niu.edu/~dattab/math435/HW4.pdf
