How display formulas correctly in beamer?

[Stefan Kottwitz]

What is incorrect? What is it that you think it's not ok?

beamer is different, and you did not make it yet in the beamer way - beamer pages are slides within a frame environment. There is no frame here.

[Stefan Kottwitz]

beamer displays math formulas with a sans serif font. You can switch to serif math, like article does, by choosing the serif font theme:

\usefonttheme[onlymath]{serif}

Then you can see the missing integrals, sum signs and further symbols again.
