You're welcome. The truth is that many things in geometry, algebra and calculus are strongly connected to modeling and understanding the world we live in or making calculations easier, but it isn't always easy to communicate that. Especially in preuniversity classes there tends to be (in my experience) a lot of focus of how things work, but not why, because it is more important to get the pupils capable of answering the questions which will be on the tests, instead of teaching them the method in which the result can be found.
I am not saying that it could be done the other way necessarily; it's likely more achievable to get the class to remember a few rules about the derivatives of a small set of functions than to teach them about the definition of a derivative, the epsilondelta definition of a limit and how to handle limits with indeterminate form (where if you just substitute the value you get e.g. 0/0).
But don't let that stop you from asking for more information. I don't know how good your math teacher is, but if they at least aren't so prideful that they cannot admit to now knowing an answer, then they should at least be able to point you in the right direction to finding more information. It may be easier to talk to them after class (when they don't have a large group of people to justify themselves in front of). It may also help if you ask them where to turn for more information, instead of asking them to explain it.
And just remember, there's a lot of good sources on the Internet for learning math. Again, KhanAcademy has a lot of videos on a wide arrange of topics (not just math) and there are many others who upload lectures to YouTube. But sometimes you need the help to even know what to ask and in those cases turning to humans instead of search engines will definitely be of help.
