    Does the Series $\sum\frac{2}{2^{n}}$ Converge or Diverge?

    Sorry fellas the question should read Does the series \sum\frac{n}{2^{n}} converge?? (Note that bounds on the running index n are from 1 to infinity) I have tried ratio test but it returned a value of 1 (showing nothing). I can see from the table function on my calulator that...

    Prove Even Integer for Natural Number n: Induction

    Use mathematical induction, to prove that \frac{n^{3}+5n}{3} is an even integer for each natural number n. I am fimilar with proof by induction but in most of the question that I have done have a LHS = RHS which seems to simplifiy things a little bit. Any help would be appreciated...

    Z transform of a discrete filter

    The question is to find the difference equation relating u(k) and y(k), which are input and output respectively. H(Z) is given as H(Z) = \frac{1+(1/2)z^{-1}}{(1-(1/2)z^{-1})(1+(1/3)z^{-1})} Solution that is given: y(k)-\frac{1}{6}y(k-1)-\frac{1}{6}y(k-2) = u(k)+\frac{1}{2}y(k-1)...

    MATLAB Truncating a Number to 5 Significant Digits in MATLAB

    Taking the base 10 is to find out how many times you would have to multiply by 10 to get the number. As i understand it to be. I am still a little trouble with getting the missing logic. Can you push me just a little bit further.

    How to Truncate Numbers to Five Significant Digits in MATLAB?

    Write a Matlab Function file that takes one integer in and converts it to an integer with only 5 significant digits. Eg Trunc(123)--------ans=123 Tunc(123345678) ----ans=12345e+03 ---------------------------------------------------------------------------------------- My thoughts First...
