Answer:
x= b-a/2 + b+2/ t= u/2 (3- u^2
Step-by-step explanation:
It is calculated by increasing the number of partitions to double from 2 to N=2n.
In the case of non-analytic at endpoints of f(x), you can calculate by Midpoint rule.
In the case of a periodic function, you can calculate by Non-linear substitution in x.
