Estimate 1 13 cos(x2) dx 0 using the Trapezoidal Rule and the Midpoint Rule, each with n = 4. (Round your answers to six decimal places.) (a) the Trapezoidal Rule (b) the Midpoint Rule

(a) 4.152698

(b) 3.215557

Step-by-step explanation:

(a)

n=4, so :

Each subinterval has length :

Therefore the subintervals consist of:

Now, the midpoints of these subintervals are:

Hence:

(b)

n=4, so :

Each subinterval has length :

Therefore the subintervals consist of:

[1,5], [5,9], [9,13]

The endpoints of the subintervals consist of:

5,9

Hence:

54.864 meters
