+108 Forum,
It seems as my previous post(entitled PreCalc Help) has gotten 19 views, and I'm just wondering if it should have been answered by now. I just want to let you know that I have a deadline with these problems and would love some explanation. I've tried using the double and half angle formulas, but I always get stuck! So please guys if you could help me ASAP that would be much appreciated. Thanks! - BasicMaths
