Calc Problem
The function f is defined by
f(x)=
(sinx)/(x) , x ≠ 0
1, x=0
A) at what points does its graph cross the xaxis?
B) What is the relation between x and tanx at points x≠0 at which f'(x)=0
C)What is the behavior of f as the absolute value of x approaches infinite


sry, just to clarify, is the same as which is zero, correct?
