Another question concerns acquiring mathematical vocabulary: Acquiring mathematics vocabulary in Norwegian
However, mathematics also includes plenty of formal expressions, such as f(x, y) = (4^x - y^3)^7, and the way to speak these out loud does not follow from knowing the vocabulary. Each branch of mathematics has its own formulas and expressions - matrices, partial derivatives, iterated integrals, commutative diagrams, and so forth.
What are good resources for Norwegian (bokmål or nynorsk) or systematic ways of finding such resources?

A good answer there suggests using videos, but finding videos that contain a particular expression, especially something used in higher mathematics, is not trivial.
