Not too easy. Not too difficult.
Professor Rowley was super helpful, and genuinely seemed to want to help everyone. I'm not a math person, but when I stopped by during his office hours (DO IT!), he was very patient and went through my questions slowly to make sure I understood the concept. Also, there wasn't much homework to actually hand in, and the projects he assigned as "group work" could be done individually if preferred.
Professor Rowley is pretty funny, so that made class less mundane. Also, I took high school trig, but the textbook he used dealt a lot more with circular trig, which I'd never had much experience with, so that was new.

Advice for students:
Absolutely go to office hours if you feel the least bit unsure of anything, do the practice problems he recommends for homework, and take good notes because the textbook examples are confusing by themselves.
