I think the best translation of "trivial" when used amongst mathematicians is that it is something you should be able to figure out with your current knowledge without too much difficulty (though it might require an hour of thought). Said in another way, you don't need to learn/develop new tools or techniques for something that is trivial.

Of course this is not when most people think when they hear the word so really it's a term of art that should probably be avoided when talking to non-mathematicians.

As i read through my old uni maths notes there are often wild leaps from a to e along with a little scrawl saying "trivially" or "obviously". They may have been true once, but god dammit 21 year old me was a knobber
