interesting... How do I get the formula for finding repeating length in an arbitrary exponential X^N.

I am looking to find an arbitrary digit of let's say 23^234. This one has 219 digits. so let's find the 187th digit... This isn't homework or anything, I just think it would be interesting and I couldn't find it on google. I would rather use simple number theory that can be taught to a...

Homework Statement by what fraction must you change the length of the pendulum to make it run true if it loses one minute every hour Homework Equations t=2pi/sqrt(g) * sqrt(l) The Attempt at a Solution I know that I am losing 1 second every 60 seconds so I need to shorten the period...

he also doesn't know whether m/b will be an integer or not. I am guessing you are reading an introductory number theory book. you should refrain from dividing as much as possible in your proofs. modding out is acceptable later when you start doing it, but don't divide unless you know that...

Hello I am appealing to the computer savvy bunch here and asking for a graph. I need the graph to show a function that is of the form (Acos(x)+Bsin(X)) it can be simple... just anything harmonic I dont' even need the function you can just draw it. and then I need a polynomial that has the...

no you will be all take different exams... think about it. how could they schedule it so that the kids in cali -8gmt could take the same exam as the kids in florida -5gmt? schools really aren't organized enough to work that one out. it is not cheating to look at old exams and the minute they put...

I am meeting an advisor later this week. any important questions I should ask?

hey, so I am going to be done with all the requirements of a math major by the end of this term and have another year left. I can't graduate cause I don't have enough credits. I don't think I want to go to graduate school for math and am considering going to graduate school for engineering...

good luck finding a course called calc IV. i really hope your school doesn't call it that lol. but yeah I never felt like I was going to do bad. most people who do physics as a major are pretty good at it and do fine in their first year. you basically retake mechanics and E&M if you don't...

I am in my junior year and am taking graduate logic and algebra courses next year. out of all my undergraduate classes I enjoyed these fields the most and am looking forward to studying them in more detail. when I did physics I was just so good at it that i enjoyed it. I enjoyed taking quantum 1...

Hey so I am a passionate math major and am pretty good at it. But I have been told several times that if I don't want to teach then I probably shouldn't go to graduate school for math. I am good with computers but hate programing. love physics but hate lab work. so with my skills what...

Hey so I am entering my senior year next year and am wondering what courses to take. If i just take what I like then it's an easy choice but I am a little worried as to what graduate schools will think of my decision and the overall benefits and disadvantages. first choice is the take under...

I am not sure if i understand the question anymore after reading your hint. what do elements in K(u) look like?

look up the taylor series for sin and cosine and write the one for tan. Now factor out X^3 from the top and take that limit as X goes to Zero

Homework Statement so this is a challenge problem that I need help getting started with. given K a field and K(t) a quotient field over K. let u=f/g for f,g in K(t). IF [K(t):K(u)] is finite then it is equal to max(deg f, deg g). Why is this true? Homework Equations K(t)----K(u)----K...
