Mathe Formelsamlung – Mailbase Blog

Thanks to MathML and MathJax, it was possible for me to write down a small formula collection quickly from memory.
Maybe I will extend it so that it will be of real use in the future.(Dank MathML und MathJax war es mir möglich, eine kleine Formelsammlung schnell aus dem Gedächtnis aufzuschreiben.
Vielleicht werde ich es so erweitern, dass diese in Zukunft wirklich von Nutzen sein wird.)
