I can already tell this might be a simple and silly question but I want to verify before I get too deep with it into my anki.
Im using the practice sentence: これが実験 の結果けである to remember the purpose of である.
Is it \*just\* the informal version of です？
（just a little add-on, if it does just mean informal です, what is the difference between である and がある?)
(((im 95% sure it is, but id like to verify with someone further along than I am. I learnt solely text book \~keigo\~ but now that im living here im finding it hard to switch to informal speech with friends so Im really trying.)))
