I place the following command into mathematica
Plot[Tan[x], {x, 0, 10}, PlotRange \[RightArrow] Automatic]
This is ripped straight from the mathematica site and I do not get a graph, instead it keeps telling me
Plot::nonopt: Options expected (instead of PlotRange\[RightArrow]Automatic)
beyond position 2 in Plot[Tan[x],{x,0,10},PlotRange\[RightArrow]Automatic].
An option must be a rule or a list of rules. >>
How to fix?
What I want to do is use plot range to change the view of my graph. For example change it from the default setting to say {{1,4},{6,7}}
Any help much appreciated.
