Adding that looping effect is pretty easy. So instead of going to your "stop" block, all of the arrows that are currently going to it would instead go to another decision box (like the ones you have determining the size of the numbers). This box would state something like "Repeat Process?" and...

Hi! Yes, it looks correct. But if you want a proper flowchart you should have that final "False" going somewhere. I would suggest using the "Equal" option to be the recipient of that false arrow, and have it go to your "stop" block. A flowchart is your psuedo-code essentially, and a code...

Yes - what Lasker said makes a lot of sense. I think a variety of people here are trying to connect the "numbers" and "counting" aspects of math with chess. I think these abilities are loosely connected but ultimately trivial when compared to the logical and deductive mindset that both...

Well, see if you can take a stab at it. The nature of the numbers should make you think factorials. Using that intuitive leap, try to logic out a way to - as vela suggested - plug in n and receive the correct values.

From the work done already, it looks to be the first option. Could you explicitly state the entire question, also? Often times with acceleration/velocity problems the manner in which the problem is set up/interpreted can account for the sign differences that using strictly mathematics doesn't...

Try simplifying your square root expression more that you already have, and you'll find you have the same answer.

Well, how would you define amplitude and phase distortion? What are the frequencies that each of the two signals you listed carry? Notice your graphs have an x-axis of "frequency." When you look at the particular frequencies that your input signal has on the graphs of the channel, what are...

Ahhh... I was not aware of that notation at all... definitely makes a lot more sense now, good find.

Perfect. Now how would you incorporate that with getting those particular initial terms in a sum? How could you then make the sign change each time?

Well if you think about convolution - what it's doing graphically - you are shifting one of the waveforms over the other. This is the tau, but the 't' is the so-called 'limit' you're integrating to when moving one of the said waveforms across the other - presumably to infinity, which of course...

Series can definitely be tricky. Things to look at first - with a series such you need to look at distinct patterns in the numbers given to you. The first thing that jumps out at my eye is that the sigh (+ or -) alternates each term. What way do series that do that are generally...

So true... *sigh* haha But anyways, perhaps it'd be easier to think about getting the answer if we did the shifting in the cosine term: y(t) = \int\limits_0^t cos(t - \tau)\mathrm{d}\tau Now using a couple trig identities... y(t) = \int\limits_0^t cos(\tau)cos(t) + sin(t)sin(\tau)...

Hmm... here's how I'd go about it - y(t) = \int\limits_0^t h(t-\tau)q(\tau) \mathrm{d}\tau where h(t) = 1 and the limits have been adjusted accordingly. Then, y(t) = \int\limits_0^t cos(\tau)\mathrm{d}\tau Which of course leads to the simple integration of: y(t) = sin(t) Which...

Hello. First of all, when putting code in the posts, there's a nifty little command of ['code']insertcodehere[/'code'] that you can use that really tidies things up (without the apostrophes of course). So it'd look like this: Hv=[1,2,3,4,5] for i=1:5 tspan=[1 30] h0=Hv(i)...

I think you need to take some intermediate steps. First you need to create a program that simply generates and outputs in a fashion that you and we can see, the Fibonacci sequence. It may be worth your time to see if you can spit out the appropriate numbers inside or outside the while loop...
