Double/Half Angle Difficulty.Hey there, I'm not sure where the majority of this community reside, but I'm David and I live in England. I study Maths at A2 Level, (C3). I'm not sure if that's what it's called overseas but I hope it's the same or there's an equivalent. Last edited by Tredici (20051213 07:35:54) #2 20051213 07:36:27
Re: Double/Half Angle Difficulty.cos (A+B) ≡ cosAcosB  sinAsinB Why did the vector cross the road? It wanted to be normal. #3 20051213 07:47:13
Re: Double/Half Angle Difficulty.In the time it took you to do that for me, I had a quick browse around the forum, I don't really know what to say. All I can say is you're all incredibly good at maths, and I really hope you don't mind a not so strong mathematician like myself crashing your parade.

Re: Double/Half Angle Difficulty.What a great thankyou! I'm sure no one minds you 'crashing our parade'. There are loads of people here who never say anything related to maths anyway, so you're actually one of the better people! Why did the vector cross the road? It wanted to be normal. #6 20051213 10:27:55
Re: Double/Half Angle Difficulty.Tredici, you are nowhere near a 'complete amateur'... don't worry! Everyone is welcome, so you don't have to feel like you are barging in. #7 20051213 19:17:10
Re: Double/Half Angle Difficulty.what is "Maths at A2 Level, (C3)"??? #8 20051213 23:27:14
Re: Double/Half Angle Difficulty.A2 is the second year of Alevels, and C3 is the 3rd module in the core section of the maths Alevel. Why did the vector cross the road? It wanted to be normal.
