Trigonometric Limits

Graph the function f(x){sin pi/x if x is not equal to o
{0 if x = 0

where -0.2<=x<=0.2. then graph f(x) where (x) varies over a smaller interval, for example, -.06<=x<=0.06. determine lim as x approaches o of sin(pi/x) if it exists. describe in a paragraph the behavior of the values of f(x) near x=0.

Solution Summary

A trigonometric limit is found. The solution is detailed and well presented. The response was given a rating of "5/5" by the student who originally posted the question.
