(a) Write a computer code for the procedure tri for solving a tridiagonal system as (b) Calculate how many long arithmetic operations (multiplications and divisions) are (c Numerically verify your calculation by running several examples. Note that you (d) [Sec. 2.3 #C4] Test tri on the following system of n equations for n-50: described in the pseudocode provided in the text involved in this procedure. will need to modify your code tri so as to count the number of long operations r 0.5 r2 0.5x,-1+0.5 2.0 (2siSn-1) = 1.5 Note that the exact solution is obvious
