Discussion Overview

The discussion revolves around the capabilities of online tools like QuickMath and software such as Matlab for solving mathematical equations. Participants explore the effectiveness and limitations of these tools in the context of higher-level mathematics and equation solving.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses satisfaction with QuickMath, indicating it helps them solve equations.
  • Another participant critiques the tool, suggesting it does not provide explanations for how problems are solved and is limited to trivial equations.
  • A different participant defends QuickMath, arguing it is effective for minimizing effort on problems when used alongside an online integrator.
  • Questions are raised about Matlab's capabilities, with one participant suggesting it can solve a variety of equations.
  • It is noted that Matlab is more numerical in nature, while other tools like Mathematica and Maple are mentioned as being better suited for solving algebraic equations.
  • Participants acknowledge that comprehensive software packages are superior to online tools but also highlight their higher costs.

Areas of Agreement / Disagreement

There is no consensus on the effectiveness of online tools versus more comprehensive software packages. Participants express varying opinions on the usefulness and limitations of QuickMath and Matlab, indicating a mix of agreement and disagreement regarding their capabilities.

Contextual Notes

Participants mention specific limitations of QuickMath, such as its inability to provide numerical answers for certain equations. There is also a recognition that the tools discussed may not be suitable for all types of mathematical problems, particularly at higher levels.

FACT: THIS IS HELPS ME! :biggrin:

Hmm, shame, I thought it might be one that explain how problems are solved. There are lots of solver programs out there that do this kind of thing, some with a vast array of other things they can do.

At higher level mathematics 'solving equations' generally isn't that interesting and certainly not the trivial ones this can only do.

Oh, won't even give me a numerical answer for something like:

x^2 - 40 = e^x

Oh, I dunno, it's fairly good for what it does. Together with the online integrator, I think we have a good set of tools to minimse the effort we spend on problems.
 
What about matlab? I had the impression that this tool could solve quite a few type of equations.

Matlab's more numerical.

The above link looks like it uses Mathematica - this and Maple are both pretty good at solving algebraic equations.

Of course, the complete packages will always be better than the online intgrator and this tool, but they are much more expensive :wink:
