# Label x axis in radians WolframAlpha

I am trying to graph a trig function in WolframAlpha. I want the x axis to show radians. It will do this for a basic function, such as $y=\sin x$, but for many functions it will just label the x axis from -10 to 10. I have googled this and this is the best I can come up with:

plot sin (x/2 -pi/16) ,Ticks ->{{-pi, -pi/2, 0, pi/2, pi, 3pi/2, 2pi, 5pi/2},{-1,1}}

It doesn't work, WolframAlpha just plots the function from -10 to 10 on the x axis.

For more sophisticated plots WolframAlpha is not the best option, I only use it for a first idea of the function. Never the less using Mathematica Syntax might help.

At least the PlotRange you can chose via

Plot[ Sin [x/2 - Pi/16], {x, -Pi, 5 Pi/2}]


which gives you this

If you have Mathematica you have a lot more options for Plots, using the command

Plot[ Sin [x/2 - Pi/16], {x, -Pi, 5 Pi/2},
Ticks -> {{-Pi, -Pi/2, 0, Pi/2, Pi, 3 Pi/2, 2 Pi, 5 Pi/2}, {-1, 1}}]


gives you

is the same possible in "maxima"? – Vikram Aug 25 '13 at 9:35
I don't konw maxima i am afraid – Dominic Michaelis Aug 25 '13 at 9:42
Thanks for the tip about setting the Plot Range. I don't have access to Mathematica. It would be good to find a free piece of software that does allow me to specify the axes how I wish. – mikoyan Aug 25 '13 at 15:46
@mikoyan I guess there are tons of free software for this. Even $\LaTeX$ can do this if you use packages like TikZor others. – Dominic Michaelis Aug 25 '13 at 15:51
Yes, but this does not keep sub-ticks... – Alexey Bobrick May 2 at 14:07
