Arithmetic sequence help?? :( it's so difficult?
Hi, The 3 numbers are x - a, x, and x + a. If the sum of the first and third is 10, then x - a + x + a = 10 2x = 10 x = 5 <==second number If the product of the first and second is 15, and we already know the second number is 5, then 5z = 15, so z = 3. If the first number is 3, the second number is 5, then the third number must be 7. <==ANSWER I hope that helps!! :-)
Determine an expression for an arithmetic series ? :/?
Determine an expression for an arithmetic series ? :/? Determine an expression for the sum of the terms of an arithmetic series with general term tn=3n-2? I'm not trying to like skip homework but like I am just looking for an explanation for this , I know its Sn=n/2( 3n-1 ). It's the only question I don't get in my homework like I don't get where the t1 went !! please help me !!! I appreciate it a lot !!! Please give me an answer that is for an 11th grader cos I just began 11th grade and don't know much )=
Should someone with an IQ of 160 be a genius at math naturally?
No.It’s impossible to measure the ability of a brain in every area with a single metric. IQ is just an overall measure and doesn’t tell you anything about specifics.IQ is like price of a computer. A computer is supposed to be good if it’s expensive. But, do we know it’s specifics? How about the software inside it?For example, I found “linear algebra” and “numerical analysis” stupidly easy, I aced them without even attending to the class, I understood everything completely just by skimming through books. On the other hand, I failed “differential equations” 2 times, and I will take it for the 3rd time next semester.Every brain works differently. I was a natural genius at linear algebra and numerical analysis, maybe due to their algorithmic nature. But a complete moron in differential equations. Some of my friends are exactly opposite.
How can I be a genius in mathematics, please answer I am desperate?!?!?!?!?
Maths has always been my weakest subject. I have always wanted to be 'amazing' at it but I just can't, I am improving but I am not the best in my class, I wish I was. It is important for the career I want to do. I know you have to be naturally gifted in math, but what can I do to match the grades of those who are gifted? I know my main problem with maths is understanding and applying concepts to exams. Please how?! Please DO NOT answer with the following: Study hard, work hard, you're either born with it or you're not, get a tutor. Thanks.
Find the missing terms in the the geometric sequence 5, _, _, 20, 48?
48/20 = 12/5 = ratio 20/(12/5) = 100/12 = 50/6 = 25/3 25/3 /( 12/5) = 125/36 125/36 /(12/5) not equal to 5 then 5 not in this geometric sequence
How do math geniuses understand extremely hard math concepts so quickly?
Some years ago I was doing a penetration test for a large mobile operator's voicemail infrastructure. The test in itself took about 5 minutes from the moment I started till the moment I was able to get into the system and change the default welcome message to something of my own. I presented my findings to the local manager in charge and, surprisingly, her reaction was - "so you expect us to pay you 2000€ for 5 minutes of work?" My answer, although a bit of a cliche, was this: "You're not paying for those 5 minutes. You're paying for the amount of knowledge gathered over the years that allowed me to figure out in less than a minute what's the problem with your voicemail." As Satvik Beri perfectly described in his answer, when you spend most of your time focusing on a specific issue, whether that's math, information security, programming or anything else - you gather enough experience to start figuring out things in a snap. That doesn't make you special, nor innately talented - just a really hard worker and extremely passionate about what you do. Think about that the next time you feel cheated by a consultant who solves your problem in 5 minutes.
What's the likelihood that Albert Einstein taught algebraic geometry?
Zero, if you ask me. Einstein was interested in mathematics only to the degree required to help him with his particular physics. None of the 4 seminal papers of his golden year 1905 had a substantial amount of math in it, although his version of special relativity did require a solid understanding of Maxwell’s electrodynamics (which involves partial differential equations). For his work on general relativity a substantial amount of differential geometry was required; people say that he called his friend Marcel Grossmann for help with that.He did a lot of calculations of the most complicated form conceivable, which provoked David Hilbert, his competitor in the race for the GRT, to state that he was the hell of a computer…Algebraic Geometry in Einstein’s days was a small area of mathematics, with Oscar Zariski as probably their best known representatives. Commutative Algebra, as the most influential tool in AG, was still in its development, and the big take-off of AG took place only after WWII with the works of Grothendieck.So summarizing: wrong subject, wrong timing. And Albert Einstein was a genius and an eminent physicist, but not the universal genius in command of the all science of his time.
Who is the most genius person alive?
Terence TaoWith an outstanding IQ of 230, Terence Tao, was teaching 5-year-olds how to spell and how to add numbers – when he was 2!!!!When he was merely 10, he began participating in International Mathematical Olympiads and won a bronze in 1986, silver in 1987 and gold in 1988, becoming the youngest ever gold medalist in the Mathematical Olympiad!By the time he was 16, he had earned his Bachelor’s and Master’s degree – he got his Ph.D. at 20!Now details about him :Terence Chi-Shen Tao FAA FRS (born 17 July 1975) is an Australian-American mathematician who has worked in various areas of mathematics. He currently focuses on harmonic analysis, partial differential equations, algebraic combinatorics,arithmetic combinatorics, geometric combinatorics, compressed sensing andanalytic number theory. As of 2015, he holds the James and Carol Collins chair in mathematics at the University of California, Los Angeles. Tao was a co-recipient of the 2006 Fields Medal and the 2014 Breakthrough Prize in Mathematics.He is known for:Green–Tao theoremErdős discrepancy problemCompressed SensingTao's inequalityKakeya conjectureHorn ConjectureHere are the list of awards he has received over the years :Jeez!It would take me three lives to even come near to his tally of awards, even if I work 28 hours a day….(btw my IQ is 30 ;) {JK}I wish I could be like him…Cheers.~Mid.{Ps: I am a new writer on Quora so all suggestions and corrections are welcome. :) }Sources:https://en.m.wikipedia.org/wiki/Terence_TaoGoogle Images
