Integrand routine.
Calculates e~x/2.
Calculates m.
Calculates (x/2)me
Labels used: A, B, and C.
Registers used: R0 (row), Rj (column), R2 (n), R3 (a), R4
), and
Matrices used: A (x(^ + l)), B (f(x(k))), C (F(xw)), and D (d(*>).
Now run the program. For example, choose the values n = 11 and
a = 0.05 . The suggested initial guesses are x^ = 3.25 and ^2<0) —
20.5 . Remember that the display format affects the uncertainty of
the integral calculation.
