Is it possible to see a more carefully rendered version of the formulae?

Yes! Click on any formula to see a more detailed rendering.

Depending on your browser or browser settings, you may need to

1. right-click on a formula
2. Select "Format" --> "MathML"
3. Select "Settings" --> "Zoom trigger" --> "Click"
4. Select "Settings" --> "Zoom factor" --> "200%"
5. Select "Settings" --> "Math Renderer--> "MathML"

This should need to be done only once.
