"Adding Complex Numbers is very similar to adding vectors..." Once again Prof. van Biezen, another gem I can pass on to my students.

The way you explain things is so easy to understand. I was wondering if there is a way I could get my hands on your Trig and Precalc tests to practice with? I'm an adult learner trying to get into college level Calc 1 trig after NOT taking HS pre calc and trig but learning on my own the past year. Want to make sure I master everything
