Guest wackeen Posted November 15, 2005 Share Posted November 15, 2005 can anyone give me a simpler explanations about Euler's identity? the explanation that can be found over the net are very complex. thanks.<{POST_SNAPBACK}> There's an extension of the real number system called the complex numbers. The numbers in this larger system can be expressed in a number of ways: 1) a+bI2) r cis t In handling the more powerful second type of notation, there are 'rules' to follow. But note that this is not just shorthand, but has an actual meaning. The Euler identity is the foundation for such a notation to be possible. Quote Link to comment

PageDown Posted November 15, 2005 Share Posted November 15, 2005 246 I don't know enough of number theory, so this is what I used instead to get the answer (it's real clunky, so apologies ): The largest sum possible for two 3-digit numbers is 1998, so _IF_ the sum of the mystery number and 596 results in a 4 digit number then this 4 digits would look like either of these two (since they are in geo. progression): b b*r b*r^2 b*r^3b*r^3 b*r^2 b*r b (where each digit <=9) With the leftmost digit (either 'b' or 'b*r^3') being a 1 (since we're checking the case where the sum is a 4 digit number). So now we have either of these two conditions (since the leftmost digit is a 1): b=1b*r^3=1 In the first case, if b=1 then r=1 or 2 (since in this case, the rightmost digit 'b*r^3' must be <=9, thus r can at most only be equal to 2). Thus the possible 4-digit numbers here would be 1111 (b=1,r=1) and 1248 (b=1,r=2). Subtracting 596 from these yields 515 and 652, niether of which are in arith. progress. So this case is false. If we take the second case, b*r^3=1, then b=r=1. Which again yields the possible 4-digit number 1111, subtracting 596 gives 515 which again isn't in arith. progress. so this case is false as well. So the above shows that the sum of the mystery number and 596 cannot be a 4-digit number. Ok, so now we know the sum is a 3-digit number, hence in the following form: b b*r b*r^2b*r^2 b*r b We also know each digit <=9 and since 596 is being added the leftmost digit must >=6, thus: 9 >= b >= 69 >= b*r^2 >= 6 Taking the second case, b*r^2, there are only 3 possible values allowed for r (due to the <=9 condition for each digit), hence drawing a matrix for values of b given the allowed values for r: b*r^2 b (r=1) b (r=2) b (r=3)------- -------- --------- --------- 6 6 X X 7 7 X X 8 8 2 X 9 9 X 1 ('X' marks non-valid combinations) Which gives 6 possible 3-digit numbers for the sum of the mystery number and 596: 666 (b=6,r=1)777 (b=7,r=1)888 (b=8,r=1)999 (b=9,r=1)842 (b=2,r=2)931 (b=1,r=3) Subtracting 596 from each will show that only 842 will give you a 3-digit number (i.e. 246) which has it's digits in arith. progress. Now for the first case, 9>=b>=6 ... nah, I'm too lazy, besides I've already got at least one answer <{POST_SNAPBACK}> Nope! you have to use a 4 x 4 matrix to get to it (easier solution).

arrowstorm Posted March 3, 2006 Share Posted March 3, 2006 For those of you who watch what you eat...Here's the final wordon nutrition and health. It's a relief to know the truth afterall those conflicting medical studies. 1. The Japanese eat very little fat and suffer fewer heartattacks than the British or Americans. 2. The Mexicans eat a lot of fat and also suffer fewer heartattacks than the British or Americans. 3. The Japanese drink very little red wine and suffer fewer heartattacks than the British or Americans. 4. The Italians drink excessive amounts of red wine and alsosuffer fewer heart attacks than the British or Americans. 5. The Germans drink a lot of beer and eat lots of sausages andfats and suffer fewer heart attacks than the British orAmericans. CONCLUSION: Eat and drink what you like. Speaking English isapparently what kills you. Quote Link to comment
arrowstorm Posted March 3, 2006 Share Posted March 3, 2006 This is a strictly mathematical viewpoint...it goes like this: What makes 100%? What does it mean to give MORE than 100%? Ever wonderabout those people who say they are giving more than 100%? We have all been to those meetings where someone wants you to give over 100%. Howabout achieving 103%? What makes up 100% in life? Here's a little mathematical formula that might help you answer thesequestions: If:A B C D E F G H I J K L M N O P Q R S T U V W X Y Z is represented as:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26. Then: H-A-R-D-W-O-R-K8+1+18+4+23+15+18+11 = 98% and K-N-O-W-L-E-D-G-E11+14+15+23+12+5+4+7+5 = 96% But, A-T-T-I-T-U-D-E1+20+20+9+20+21+4+5 = 100% And, B-U-L-L-S-H-I-T2+21+12+12+19+8+9+20 = 103% AND, look how far ass kissing will take you. A-S-S-K-I-S-S-I-N-G 1+19+19+11+9+19+19+9+14+7 = 118% So, one can conclude with mathematical certainty that while Hard Workand Knowledge will get you close, and Attitude will get you there, it'sthe Bullshit and Ass Kissing that will put you over the top.

Ruey Roi Posted March 31, 2006 Share Posted March 31, 2006 Drake EquationIs there a way to estimate the number of technologically advanced civilizations that might exist in our Galaxy? While working at the National Radio Astronomy Observatory in Green Bank, West Virginia, Dr. Frank Drake conceived a means to mathematically estimate the number of worlds that might harbor beings with technology sufficient to communicate across the vast gulfs of interstellar space. The Drake Equation, as it came to be known, was formulated in 1961 and is generally accepted by the scientific community.N = R* fp ne fl fi fc L where, N = The number of communicative civilizations R* = The rate of formation of suitable stars (stars such as our Sun) fp = The fraction of those stars with planets. (Current evidence indicates that planetary systems may be common for stars like the Sun.) ne = The number of Earth-like worlds per planetary system fl = The fraction of those Earth-like planets where life actually develops fi = The fraction of life sites where intelligence develops fc = The fraction of communicative planets (those on which electromagnetic communications technology develops) L = The "lifetime" of communicating civilizations Frank Drake's own current solution to the Drake Equation estimates 10,000 communicative civilizations in the Milky Way. Dr. Drake, who serves on the SETI League's advisory board, has personally endorsed SETI's planned all-sky survey. Quote Link to comment
