9) Provide the commands for a function file that plot the following: rsin(!), 22 and -z?. Investigate the limit as x approaches zero from the right and left for the function rsin(). What do you think the limit is as x approaches zero? Using the squeeze theorem, explain why the limit is what you found? 10) Provide the commands for a function file, that implements the limit definition of the derivative, and graphs the function sin(x) + 5 and the derivative function of sin(x) +5. What is this derivative function? How can you tell by the graph? 9) Provide the commands for a function file that plot the following: rsin(!), 22 and -z?.
