Re: Series and Progressionskrassi_holmz, although I don't see any serious mistake in the way you started, I am not fully convinced with the proof. I shall wait for a few more days before posing the solution. Character is who you are when no one is looking. #4 20060228 16:38:34
Re: Series and Progressionsp,q and r are in Arithmetic prgression, so Where's my mistake? Last edited by krassi_holmz (20060228 16:46:07) IPBLE: Increasing Performance By Lowering Expectations. #5 20060228 17:05:48

Re: Series and ProgressionsSP #4: the ball is dropped, so it doesn't travel anywhere. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #14 20060303 23:11:41

Re: Series and ProgressionsThis is how the problem is solved in a different way. Character is who you are when no one is looking. #17 20060304 22:33:10
Re: Series and Progressions
If you're being picky like that, then technically it travels 6m. Why did the vector cross the road? It wanted to be normal. #18 20060304 23:47:40

Re: Series and ProgressionsSP#3: q=57(1a) Solving a=2/3 or a=3/2; Then q=19 or q=57/2 But when q=57/2 the sum is negative, so: So the answer is: a=2/3;q=19 IPBLE: Increasing Performance By Lowering Expectations.
