I'm taking pre-calculus classes - learning about functions, limits and that stuff right now - and I came to $y = \sin(\frac{1}{x})$. Google represents it like this: Google_graph_of_$y = \sin(\frac{1}{x})$
But in Microsoft Mathematics it looks completely different: Microsoft_Mathematics_graph_of_$y = \sin(\frac{1}{x})$
Simply: WHY?
The second curve is $y=1/x$ and is not $sin(1/x)$. Make sure you type the parenthesis correctly.
