Penn state application question: required math coursez

“Three units of mathematics are required (four are recommended) selected from any combination of algebra, geometry, and trigonometry.”

I never took trigonometry as a full class, bur i took algebra 2 junior year and i’m pretty sure they covered some trig towards the end half of the class. Would this count? or should I select the trig box as well cause technically i did learn a half semester of it.

Does your HS have a trig class? Or is it covered in other math classes?
