# Core 2 q! Watch

Announcements
1. Hey everyone, so I have a quick core 2 related question that I was wondering if anyone could help me with...

Solve the following equations: cos^2(x) = (7^1/2) / 13

Am I right in saying that cos(x) would equal + ((7^1/2) / 13)^1/2 as well as
-((7^1/2) / 13)^1/2 ?
2. I thought you meant core 2 quad...
