Hi,

I'm trying to find my way around using pdsolve. The problem I have now is how to handle the result it return me. From the psdolve help page, for example, we have the following equation returned (eq. 1.2) :

f(x, y) = _F1(x^2+y^2)

Dear friends,

I am stuck with this question.

X, Y AND Z are the angles of a triangle and f is a function defined as

f = sin X sin Y sin Z

1) Express f in term of X and Y only
2) Prove that f is a maximum if the triangle is equilateral

Hope someone is able to help me through.
Thank you.

Try this out:
dt:=[2.5, 3.9, 2.9, 2.4, 2.9, .8, 9.1, .8, .7, .6, 7.9, 1.5, 1.8, 1.9, .8, 6.5, 1.6, 5.8, 1.3, 1.2, 2.7];
Statistics[Histogram](dt);

You can see the tickmark for frequency/vertical axis is wrong. The leftmost bin hits somewhere more than 0.8. Option "frequencyscale=relative " does no help. But option "discrete=true" or change some setting about bin, such as bincount ..., can help. It seems a bug? Or my understanding about histogram is not right?

I have multiple XY pairs from multiple sensor data which I would like to display on the same plot.  I can easily do this in MATLAB, but referencing Chapt 5 of the User's Manual indicates ways to plot multiple plots when plotting relations, but nothing I found pertains to actual numeric data sets.  The only plot command I found was "PointPlot" & it appears it can only plot a single data set at a time.

Any suggestions?

When I press shift+enter, I get a new line, but how do I remove the line ? (highlighting it does not always work, so I can't seem to manually delete it)
