Ahhh...I was confused for a second but I was doing the binomial theorem wrong. Thank you so much that helped tremendously!

Hi All, I'm terribly stuck on this problem. We were asked to calculate how many hand gestures are possible, keeping in mind that a hand gesture consists of raising one or both hands and extending some fingers (note: raising just a fist is also considered a gesture). I started this problem by...

Hi, I'm currently taking a Discrete Mathematics class and cannot seem to work out this one problem, we need to find the x^10 term in order to determine its coefficient of the equation f(x)=(x+x^2+x^3+x^4+x^5+x^6)^3 I know the answer is to be 27 from a previous problem (we are to use this method...

I guess I thought the limit of infinity/infinity would be 0, but now that I look at it more I feel like the limit would be 2, and because we have the (-1) in front, would the limits be -2 and 2?

Hi, I am asked to find the limit points of the given set A A={((-1)^n)(2n/(n-4))} so far I think 0 is a limit point, but I can't figure out if there are any more than just that one. I believe every point in A is an isolated point, and that this set is open because every point in A...

Analysis Proof Help! If anyone could give me a hint on how to start this I would appreciate it! I am struggling with proofs! Thanks! Given a sequence (asub(n)) s.t. (i) the sequence is decreasing (ii) the limit of the sequence is 0. Prove rigorously that an is greater than or equal to 0...
