b) Trapezoidal Rule
We have that a=0, b=2, n=8.
Divide the interval [0,2] into n=8 subintervals of length Δx=1/4, with the following endpoints: a=0,1/4,1/2,3/4,1,5/4,3/2,7/4,2 = b
Now, we just evaluate the function at these endpoints:
Finally, just sum up the above values and multiply by Δx/2=1/8
Answer: -3.43359375
a)
We have that a=1, b=2, n=8.
Therefore, Δx=(2−1)/8=1/8.
Divide the interval [1,2] into n=8 subintervals of length Δx=18 with the following endpoints: a=1, 9/8, 5/4, 11/8, 3/2, 13/8, 7/4, 15/8,2 = b
.Now, we just evaluate the function at these endpoints:
similarly we find others
Finally, just sum up the above values and multiply by Δx=18:
Answer: 1.18177795410156
c)simpsons rule:
We have that a=0, b=2, n=8.
Therefore, Δx=(2−0)/8=1/4.
Divide the interval [0,2] into n=8 subintervals of length Δx=14, with the following endpoints: a=0, 1/4, 1/2, 3/4, 1, 5/4, 3/2, 7/4, 2 = b.
Now, we just evaluate the function at these endpoints:
Finally, just sum up the above values and multiply by Δx/3=1/12
