    Detecting Missing Teeth on a 60-1 Encoder Wheel with an Arduino

    If the wheel spins at a constant rate, then you can use this information to your advantage (im assuming VR sensor means variable reluctance sensor, which i just looked up on wikipedia). If there is no steady state (wheel can spin at vastly different rates at any moment), then I'm not sure how to...

    Schools Going to grad school after a few years of working?

    I was just wondering if this is a common thing that people do. I am a junior in college and I had a software engineering internship and enjoyed it very much and I think it'd a career i'd enjoy. However I've always wanted to get a phd in computer science and do research in computer graphics. At...

    Relation and order relation question

    well honestly i don't know lol. according to the two conditions given by my book for a relation to be an order relation, this set of ordered pairs should be an order relation since it satisfies both. however i just can't figure it out what it is exactly, if it even is an order relation. it...

    Relation and order relation question

    under "relevant equations" in my first post, at the end the two conditions given by my textbook for a relation being an order relation are given. a relation * (* can be anything) is an order relation if it satisfies these two conditions condition 1 for every (a,b) only one of these...

    Relation and order relation question

    ah i think i get it. so then it is an order relation it satisfies conditions 1 since each (a,b) only satisfies only one of the three there is only aGb for example there is only 4G1, but there is not 4 = 4 (4,4) nor is there a 1G4 (1,4) then it also satisfies condition 2 since if we try to...

    Relation and order relation question

    Homework Statement Let A = {1, 2, 3, 4} Let G = {(4,2), (4,1), (4,3), (2,1), (2,3), (1,3)} Is G a relation? is G an order relation? Homework Equations i think i should put the definitions of a relation and an order relation here. also this is from the book Elementary geometry from...

    Which Math Class is Best for a Computer Engineering Major?

    thanx a lot. i didn't know that you needed abstract algebra for number theory. I guess i will be taking that :)

    Which Math Class is Best for a Computer Engineering Major?

    Hello physicsforums next semester i have a bit of an awkward schedule because i changed majors. this left me with in a strange spot where i can take another math class. here are my choices Abstract Algebra pros +i am pretty interested in it due to some exposure in linear algebra +I...

    1-1 and onto linear transformation question

    Homework Statement Assume that T:C^0[-1,1] ---> ℝ. assume that T is a linear transformation that maps from the set of all continuous functions to the set of real numbers. T(f(x)) = ∫f(x)dx from -1 to 1. is T one to one, is it onto, is it both or is it neither. Homework Equations definition...

    How do I test for linear independence if there are only 3 equations in R4?

    assuming you did it correctly, than that shows that the vectors are linearly independent

    Limit of sequence proof (elementary analysis)

    lol that makes me feel better. i am trying to go through this book before taking analysis 1 so i don't get destroyed, but its a real pain since i don't have any proof experience.

    Limit of sequence proof (elementary analysis)

    ah thank you. i didnt think of that fact. i will try to use LaTex more. also, i just have a general question. is it normal to be awful at these kind of proofs? i was able to get all of the other proofs in the book not related to epsilon delta stuff, but for some reason i just can't figure...

    Limit of sequence proof (elementary analysis)

    Homework Statement Consider three sequences a(n), b(n) and s(n) such that an a(n) <= s(n) <= b(n) for all n and lim(a(n)) = lim(b(n)) = s. Prove that lim(s(n)) = s (n) is a subscript Homework Equations the book i am doing this problem from is elementary analysis, the theory of calculus...

    Courses Which Computer Science Course to Help in Computational Physics

    try taking a class on Numerical Methods (what its called at my university) i imagine a class on solving differential equations numerically would be very useful

    Other Should I Become a Mathematician?

    hello physicsforums.com, i just have a question about proofs in general, but i didnt think it warranted a thread and i think this is the right place to put it. if i am doing a proof and i get to the end, how do i know i am right? i am doing extra problems from my linear algebra book and from...
