# Thread: What are patterns in Trigonometry?

1. ## What are patterns in Trigonometry?

So i will soon have to do a math investigation in class, i'm quite sure we'll have to investigate patterns in trigonometry, could someone pleaseeeee help me?? i'm pretty much lost...

Could you be a bit more specific with your question? Patterns? What do you mean?

Like they give you this:
cos360=1
cos360+cos180=0
cos360+cos240+cos120=0
cos360+cos270+cos180+cos90=0
cos360+cos288+cos216+cos144+cos72=0

What kind of patterns can you find in this and what kind of equation/s can you deduce from it. That kind of stuff…
