Re: Problems and Solutions
Why did the vector cross the road? It wanted to be normal. #28 20050720 17:16:37

Re: Problems and SolutionsWow, four simultaneous equations... Why did the vector cross the road? It wanted to be normal. #32 20050721 07:41:07
Re: Problems and SolutionsBY THE WAY, since my little {hide}{/hide} tag is getting used a bit, it will soon become too late to rename it to {popup} or {boing} or whatever.

Re: Problems and SolutionsFor MathIsFuns lake problem I got 6,931,471.8055994530941723212145818 liters of water that needs to be added. #34 20050721 10:37:45
Re: Problems and SolutionsThere's a Hide tag?! Boy let me tell you what: I bet you didn't know it, but I'm a fiddle player too. And if you'd care to take a dare, I'll make a bet with you. #35 20050721 16:18:16
Re: Problems and Solutions
Was that with calculus or a more accurate version of my method? Why did the vector cross the road? It wanted to be normal. #36 20050721 17:21:56
Re: Problems and SolutionsNope no calculas or your method, I just got a tip from a friend that its related to the natural log of 2, which is 0.69314718055994530941723212145818. #37 20050721 17:27:16

Re: Problems and SolutionsWhich is greater? Character is who you are when no one is looking. #39 20050722 15:57:18
Re: Problems and SolutionsDegrees, radians or grads? Why did the vector cross the road? It wanted to be normal. #40 20050722 16:14:40

Re: Problems and SolutionsPlotting cos(sin a) against sin(cos a) in Excel gives a smiley mouth. The important thing, though, is to see whether one is always bigger than the other, and this graph cannot do that. Why did the vector cross the road? It wanted to be normal. #42 20050722 18:52:37
Re: Problems and SolutionsCos(Sin A) is always greater than Sin (Cos A), Character is who you are when no one is looking. #43 20050722 19:02:16
Re: Problems and SolutionsOoops, my bad in some calculations. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #44 20050722 20:07:33
Re: Problems and SolutionsThank you, Admin, for the neat graph. Character is who you are when no one is looking. #45 20050723 19:55:17
Re: Problems and SolutionsI just remembered a question asked to me when I participated in a quiz when I was 14 : Character is who you are when no one is looking. #46 20050723 21:04:50
Re: Problems and SolutionsWell, it has to be made up of 0's 1's and 8's (and maybe 2's and 5's that swap when reversed, depending on the writing style) Why did the vector cross the road? It wanted to be normal. #47 20050730 17:54:39
Re: Problems and SolutionsTwo candles A and B, of equal height but different circumferences, burn for 4 hours and 3 hours respectively. If the two are lit at the same time, after what time would one candle be half the height of the other? Character is who you are when no one is looking. #48 20050730 20:02:39
Re: Problems and SolutionsThis is the closest answer I could find. I get about 3 minutes more than what the picture says. Why did the vector cross the road? It wanted to be normal. #49 20050801 16:54:04
