Thanks for the feedback! I agree that introducing *Mathematica* and the Wolfram Language to students at an early age through their math courses is a good idea for both the popularization of Wolfram applications, and the overall education of the...
By default, the Mathematica Front End displays 6 digits of numbers with finite precision. It is internally using more digits for the calculations, but it only displays 6, rounding the final digit if necessary. You can changed this by going to...
Pluto is not a planet according to the IAU. If you use dwarf planets instead, you will find Pluto (along with other dwarf planets).
Many Wolfram Language functions return generic solutions. See [this][1] or [this][2] . Therefore, this result is actually what Mathematica is documented to return. Non-generic solutions can be addressed with functions like Assuming as David shows...
The Wolfram Cloud developers recently identified an issue that caused issues with signing into the Wolfram Desktop. This problem was resolved yesterday, so you should now be able to sign into the product. Please let us know immediately by...
I believe that what you actually want to do is this: Integrate[x^2 + y^2 + x y, {x, 0.0001, 0.01}, {y, 0.01, 0.5}] Note that there is whitespace between the x and y at the end of the integrand.  That whitespace is necessary - if the...
It might be more clear to you what is happening if you wrapped FullForm around the results: FullForm[curves[[1]]]FullForm[bounds[[1]]]bounds[[1]] has curly braces around it, indicating it is a list.  curves[[1]] is just...
You have a few syntax issues: First of all, "pi" is not a built in symbol in Mathematica.  Please recall that all built in symbols in Mathematica begin with a capital letter, so it should be "Pi". Also, I do not think that you are using an accepted...
I think that the issue is that NMinimize is more likely to get "stuck" in a local minimum and never get to the global one.  So it is less clever with local minima.
As Brett indicated, solving numerical problems like this is generally a two step process.  You must remove all floating point numbers from your input, and then use the WorkingPrecision option.  In your most recent example, your input includes...
