Chapter 4, Problem 68(choose chapter or problem)
Finding and Analyzing Derivatives Using Technology In Exercises 65-72, (a) use a computer algebra system to differentiate the function, (b) sketch the graphs of f and f' on the same set of coordinate axes over the given interval, (c) find the critical numbers of f in the open interval, and (d) find the interval(s) on which f' is positive and the interval(s) on which it is negative. Compare the behavior off and the sign of f'.
\(f(x)=\frac{x}{2}+\cos \frac{x}{2}, \quad[0,4 \pi]\)
Text Transcription:
f(x)=x/2+cos x/2, [0, 4 pi]
