Hello, I need some help specifying the square range of the data retrieved. Use of GeoRange or GeoRangePadding options in GeoElevationData[] function causes error: Unknown option GeoRange for GeoElevationData Here is an example call (I...
I am curious to understand why Hue[0] == Hue[1] does not evaluate to either True or False or at least some other Explanation message. Instead I get the initial expression with Color object substitution. Then using === I get False but we know that...
Mathematica does not simplify Sqrt[x^2] in expressions. Even if attempting: Simplify[Sqrt[x^2]] or FullSimplify[Sqrt[x^2]] The result remains: Sqrt[x^2] instead of just x. Am I missing something? Do I need to specify a...
In the below example: In[41]:= Factor[((1/x - 1) (1/x + 1))/((x - 1) (1/x + 1))] Out[41]= -(1/x) I need Mathematica to provide a trace of each operation taken to get to the result (possibly with the associated rule but not mandatory). ...
Hello, I want to Plot a function of x with different terms on R-, 0 and on R+ as one function rather than as a set of functions. How can I achieve that, there is no such example in the doc for Plot[]? Thank you.
I have a robot from which I can send data to my C++ program over UDP on the LAN. Now I want to send those same data (live) to Mathematica to have a live Graphical Representation of my sensor values. Is it possible? When I try to instantiate a...
Hello, I am new to Mathematica and still in the trial phase and I am having a hard time achieving something I assume would be relatively simple to do in Mathematica: What I want to do: ----------------------- - a) Import a mesh from the file...
