    calculate [tex]I=\int_{0}^{1}\cos(\frac{\pi}{2}x^2)[/tex]
    by trapeze methos in those pannels

    what is the best aproximation we can get from part A of the question?

    the solution for part A is

    my problem start with the solution of part B


    how they find [tex]T_{2,1}[/tex] for example??
    how each index plays a role in the formula
    by what formula they work on??
