Why does [math]\displaystyle\lim_{x\to 0}\frac{\sin(x)}{x}=1[/math] but [math]\displaystyle\lim_{x\to 0}\frac{\sin(\frac{1}{x})}{\frac{1}{x}}=0[/math]?
What is: [math]\displaystyle\lim_{x\to0} \frac {1}{x}[/math] ?
מדוע [math]\displaystyle\lim_{x\to 0}\frac{\sin(x)}{x}=1[/math] אבל [math]\displaystyle\lim_{x\to 0}\frac{ \sin(\frac{1}{x})}{\frac{1}{x}}=0[/math]?
מה זה: [math]\displaystyle\lim_{x\to0} \frac {1}{x}[/math] ?
