What are you supposed to do in the sine curve section on Guitar Hero 4 Vocals?
Q. Ya, we can't figure it out. the track shows a beige sine curve with echos going across the screen, and there are points racking up when we sing, but we\re not quite sure how to maximize them. Is it just a free section in which to scream for the audience, or what?

Using a buffer to program a sine curve in MATLAB?
Q. I am trying to generate a sine curve voltage program for action potential signal generating? I am new to MATLAB as my rather unprecise question shows. I was thinking of using a Buffer to store values and then running the signal off that. Any idea on how to generate a sine curve in MATLAB?

What is the transformation to map a Sine curve onto a cosine curve?
Q. I came up with: A reflection of the y=sinx over y=(pi/4). First to confirm or provide the correct answer gets Best Answer.

A. Hi, y = sin(x + /2) = cos (x) This shifts the sine graph /2 to the left, which makes it the same as the cosine graph. I hope that helps!! :-)

What is the difference between the period length and period in sine curve?
Q. I was given a table and the closest equation is y= 3sin10x. It asks to find the mean period length and then estimate the period. I thought the period is the distance between 2 closest peek, or same y-value. Like, if peek1=2, peek2=4, and peek3=6, then period is 2. But I don't get what it means by "mean period length"... Please someone help me to understand...
Asked by wildroses - Thu Jun 18 18:58:50 2009 - - 2 Answers - 0 Comments

A. Period is how long each cycle is, so you could measure each cycle and find their average. The period for sin and cos is 2 (or 360) divided by the coefficient of x so it should be /5 or 36

A. hmm!! i could help you with perspective but this... I dunno. Why not draw the curve(s) first in the foreground and you may use it as a fence (weird shape) then using straight lines connect to maybe a point in the centre (end) of the paper and draw a road that meets the sun setting with small buildings around. Take a look at some websites that have perspective drawings maybe that'll give you some ideas... Keep an open mind... Good Luck!

Asked by s.s. coolio - Sun Nov 9 15:39:39 2008 - - 1 Answers - 0 Comments

A. If you can see the curve, then you should be able to see the distance between high points or the distance between low points. This distance is the period. Frequency is simply the reciprocal of the period. So if I am looking at a sine curve that has a distance of (5pi/6) between high points, then the period of the function is (5pi/6). The frequency is (6/5pi). Period tells you "radians per cycle" and frequency tells you how much of a full cycle happens in one radian.

DO single photons display sine curve??
Q. Electromagnetic waves are shown as the charge (and magnetic fields) waving as a smooth sine curve. Is there experimental verification of such smooth sine curve?--or does it come out of the fact that maxwell equation derivation resembles a wave equation. If an individual photon is moving (and not a train of photons) will the charge curve still be a smooth sine wave? If not what does it look like. Have experiments with single photon been carried out to verify the shape of charge/magnetic waves for individual photons? Do they show a smooth curve or gaps??
Asked by lemur_monk - Sat Aug 19 02:48:42 2006 - - 5 Answers - 1 Comments

A. Neither the time nor space dependence of a macroscopic (classical) electromagnetic wave has to be sinusoidal. In fact any solution of the form f(x-ct) satisfies the wave equation for any component of the electromagnetic field, with f any function whatsoever. The form of the wave depends on the source (charges and currents) which produced it. On the other hand it's relatively easy to calculate the radiated EM field for charges and currents which have a sinusoidal time dependence and it's always possible to write any current density as a linear superposition of such fields. That's why these types of fields are important theoretically. Also, for some applications, like radio waves, the fields do vary more or less sinusoidally near the… [cont.]

A. Unless you have to include the y-axis in the picture, the sine and cosine curve are the same thing. The only difference is that they're offset by pi/2 on the x-axis. Something really simple/obvious would be a series of hills, perhaps with interesting things happening on/in/between them. You could draw a lake with a perimeter in the shape of a sine curve. You could draw someone doing math, but your teacher would probably swat you for that. ;) You could draw... a mound of gifts? You know, with a bunch of peaks and valleys in the mound that take the shape of a sine curve. You could draw a cake, or other thing with icing/whipped cream/topping that might get laid on in a sine curve pattern.

Asked by lordpreetam - Tue Aug 7 07:26:37 2007 - - 1 Answers - 0 Comments

A. Use the fact that if C is a connected set, then the closure of C is also connected. The 'sine' part of the TSC is clearly connected since it is a continuous image of a connected set. The closure includes part of the y-axis. Now, the union of two connected sets is again connected if they have non-trivial intersection. As for 'space-connected', I suspect that you actually mean 'path connected'.Any path from a point of the 'sine' part to the y-axis would have to go through every x value in between. But then, it is easy to find a convergent sequence whose image doesn't converge because of oscillations.

A. I just answered a version of this for somebody else. The benefit, of course, would be that the model seems to work and be easy to compute. The reasons it would work would be explanations of why the predator and prey functions or their first or second derivatives are something like proportional to each other.
