Has this turned into a thread of trying to find a math trick that Ether doesn’t know how to work it? If so, i want a chance to disprove it before he dose .
I have an article here one of my math professors gave me that has a dozen “proofs” that 1=2. (She gave me this after I showed her my “proof,” which happened to be in the article… I guess I didn’t come up with it first…)
… does converge. It converges because of the parentheses. The term that is being repeatedly added is (1-1). It is equal to zero.
If you remove all the parentheses, so that you have
1 - 1 + 1 - 1 + 1 - 1 …
then you are alternately adding plus or minus 1, so the sum never converges: it oscillates between 1 and 0.
The error was re-arranging the parentheses. The associative law does not always hold for an infinite sum: You cannot re-arrange the parentheses in an infinite sum unless certain criteria are satisfied.
The lack of a “p” was a typo, also, I don’t like using alt to insert symbols either, but if you use google translate to enter the text the symbol keys (;’,./]=-) are used to input special letters like vowels with accents
Also, nobody has attempted to figure out this one yet
Back in college years, my two buddies and I decided to go to Las Vegas for spring break. We piled into my Chevy Cavalier station wagon (jealous?) and headed West.
About 4am, we got to the point where we were all falling asleep, none of us were able to drive, and the car was too small to comfortably fit three guys. We found a small motel in Kansas, paid $30 for a room ($10 each), and retired for the night.
The clerk was filling out his books when he realized the motel had a policy of $25 per night after 1am. He took five $1 bills and headed to our room. Along the way, he realized we were not going to be able to split five bucks equally among the three of us. He shoved two of the singles in his pocket, gave us each a dollar, and that was that.
Here’s the issue:
We were initially charged ten dollars a piece - total of $30.
After the clerk realized his error, the room charge was $25. We paid $9 apiece ($10 - the $1 that was returned) for a total of $27; he put two dollars in his pocket for a total of $29.
