If he faces where he came from THEN turns 45 to the right....he will form a 90 where intersecting B's path

Musicmystery -> RE: A little geometry problem (10/31/2008 3:05:47 PM)
First, B is who makes the turn. Second, B would be making a 135 degree turn is such a case.

Termyn8or -> RE: A little geometry problem (10/31/2008 6:08:37 PM)
Ninety degrees would bring path B back to A at the same rate at which they diverged. If it's 135 degrees that would form a right triangle. T

Even if B is a leftist? [sorry....I couldn't resist]

Actually Mus, if we know the political leanings of the OP we can easily modify the math to suit. Media and government have been doing it for decades. That's why we are not in a recession. Constants can be variables and variables can be constants. Heck, we are on our third pi now, think they got it right this time ? T

lemmebeYourMine -> RE: A little geometry problem (11/1/2008 10:27:24 PM)
Lol, and how do you look around and decide I will make a 45 degree turn here if I walk exactly in this direction? And who wants to read crap like that anyone; Besides everyone giving helpful and or otherwise mathmatical answers to the OP. Sorry when I am reading I don't want to find a math problem that I have to figure out/visualize etc and see if the author is right. But i guess that is just me. and maybe I should leave the enthusiasts to this question. I am still not reading the story later on when it is written.

quote: ORIGINAL: Musicmystery Even if B is a leftist? [sorry....I couldn't resist] If he became a "leftist", it was something he did later in his journey, when he had acquired some sense of direction, since his first lurch was a drastic turn to the right. [8D]

If this is a woman trying to catch a guy, a guy is naturally faster than women ( why they don't race against each other), so the woman would never catch the guy. After a day, he would move on and she would never catch him before he got bored and did something else, unless he knew he was being followed and waited for her. Two people walk at different speeds, no two people walk at the same speed, its almost like a finger print. Naturally a woman is slower than a guy, and that is why women slow down men when they walk together. I don't think you should overcomplicate this, if the person has skills at tracking and following, that is what should be expressed in the writing, not some lame idea of unrealistic geometry/math. Its not like its rocket science to follow someone at a discrete distance or actively make sure your not being followed. After four pages of people making this into rocket science, I gotta admit, people love to overcomplicate simple things.

It's the fact that some people like to nitpick and i wanted to make sure the math was right. Otherwise somebody would point out how the story was not accurate. And there would be discussions on the curvature of the earth. And they would get a knee to the gut and an elbow uppercut.

quote: Right 45 and then left 45 puts him parallel. I figured it was a joke. then turns back towards his original direction 45 degress Not always. If they start out at the South Pole, then both are walking due north but on lines of longitude 45 degrees apart from each other. If B then turned 45 degrees towards A, he would be on an intercept course.

quote: ORIGINAL: blacksword404 I have a problem i need some help on. If you have two people who are standing in the same spot. They both walk off. One straight ahead and the other to the right 45 degrees. The one who went straight is A and the other is B. B walks for a full day and then turns back towards his original direction 45 degress and walks for another full day. After he finishes his path intersects with the path of A. It creates an iscoceles triangle. I need to know how long A walked to intersect with B. If the man walks 45 degrees to the right of A and then 45 degrees back from the direction of the starting point the third angle to make up the triangle must be 90 degrees since all triangles add up to 180 degrees. Person B is walking along the hypotenuse and after one day turns to walk along Opposite, person A meanwhile is walking along the Adjacent. cos45 = Adj/Hyp sin45 = Adj/(1 day) therefore Adj = Sin451 day = 0.707 days or Adj = Sin45(24 hours) = 16.97 hours. Incidentally and unsurprisingly person A doesn't have to walk a whole day to intercept with person B so why it took him more than one day who knows? sin45 = Opp/Hyp sin45 = Opp/(1 day) therefore Opp = sin451 day = 0.707 days. or Opp = sin45(24 hours) = 16.97 hours or 0.707*24 or whatever floats ya boat. No need to make life complicated. The question is slightly misleading as I read it because if the man B only turned 45 degrees back from his current bearing he would be walking in parallel with man A and the two lines will never intersect thus it must mean he turns back 135 from the direction he is facing (180-45).

stella41b -> RE: A little geometry problem (11/8/2008 4:14:29 PM)
The solution is simple. Just make B a Parking Enforcement Officer. That way he turns up where you least expect him.

blacksword404 -> RE: A little geometry problem (11/8/2008 4:20:31 PM)
I deal with them enough. No stories about them.[:'(]

FullCircle -> RE: A little geometry problem (11/8/2008 4:20:51 PM)
Take note all parking officers now take a picture of your car to prove they have put the ticket on it thus there is some ample opportunities for appearing as a pedestrian in amateur photo work.

came4U -> RE: A little geometry problem (11/8/2008 6:29:07 PM)
If they could walk non-stop, considering the earth is approx. 25040 mi in circumfrence it would at a pace of 3ish miles per hour (8346 hrs total)...take 347 days. They would have intersect at the 225 degrees point except the one guy who has an extra day of walking because he turned around and had lost a day. Depending on which guy, one can come up upon the other and beat him to that intersection. *edit to add: if the assassin was the guy walking straight, he can beat the other guy to the intersect (considering he kept going), if the assassin was was the one who went at the 45 deg angle, he travelled two days to return back to the origional starting point, he only has to return to that point on the 299th day to get his mark.
