My problem is simple. I'm working on a document which will display a few simple, mathematical formula's. I will just copy & paste those images inside my documents, presentations and whatever else but to do this, I first need to create those images first.
So, is there any good, simple to use software which can create these images?
Okay, there's the Wikipedia entry which lists quite a few applications. It contains MathCast, which is free. I just don't like it. There's OpenOffice but am already using Microsoft Office and don't need a complete second Office product just for it's math functionality. Office itself also has an equation builder but I need something outside Office which can generate bitmaps or metafiles so I can re-use the image. The Wiki contains even more applications but it's a bit of an information overload.
Since this is just an one-time use for about 15 different functions, none of them real complex, I don't really want to spend any $ on it. And also, it should be simple to use...
As an example, this image from Wikipedia:
The formulas that I need to generate are reasonable similar to this one. And although I could just use Paint to draw it, I'd prefer something more complex that will remember the formula itself, not the image. But the documentation will need images since the document will be shared with others, possibly even exported to PDF and even used in presentations. (Or even added to the HTML of a web page.)
