In Exercises 23–26, use a CAS to perform the following steps.

a. Plot the functions over the given interval.

b. Subdivide the interval into $n = 100, 200$, and $1000$ subintervals of equal length and evaluate the function at the midpoint of each subinterval.

c. Compute the average value of the function values generated in part (b).

d. Solve the equation for (x) using the average value calculated in part (c) for the $n = 1000$ partitioning.

$f(x)=x \sin \frac{1}{x} \text { on }\left[\frac{\pi}{4}, \pi\right]$

Equation Transcription:

$n\ =\ 100,\ 200$

$1000$

$n\ =\ 1000$

$f(x)\ =\ x\ sin\ \frac{1}{x\ }$ on $\left[{\frac{\pi{}}{4}\ ,\ \pi{}}\right]$

Text Transcription:

n = 100, 200

1000

n = 1000

f(x)=x sin 1/x on [pi/4, pi]
