Expert Solution
Step 1
Given that,
Interval is [0,1] and h = 0.2.
Hence the length of each subinterval is 0.2
Form subinterval as [0,0.2], [0.2,0.4], [0.4,0.6], [0.6,0.8] and [0.8,1].
The number of intervals are 5, so n = 5.
Step 2
Now we need to find midpoint f each interval:
Midpoint of [a,b] is,
the midpoint of each interval as follows:
For [0,0.2],
For [0.2,0.4]
For [0.4,0.6]
For [0.6,0.8]
For [0.8,1]
Step 3
Now find the value of a function at each midpoint,
By using midpoint rule,
Let xi be the midpoint of the interval [a,b] then the approximation is called midpoint rule approximation:
