Trigonometric Limits
Not what you're looking for?
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.
