more maths
So I am completely stumped on this
"what happens when a high frequency wave combined ,h(x) with a low frequency wave l(x) with the same amplitude and phase. The resulting complex wave r(x) is the sum of two functions or r(x) = h(x) + l(x) . " I cannot find anything in my book or the class slides on it. |

Is that not just a trig function?
sin a + sin b = [ 2 sin a+b

Do you have a graphics calculator? Just graph an equation of the resultant equation as Kuan describes.
If you dont have a suitable calculator, download graphmatica & use it. Its nice & simple.

well I think I need an explanation why that happens. This is for my "fundamentals of IT" class....
waste of time if you ask me.. I took the first test in 6 minutes and scored an A it also helps if I have the calculator in radians. Last edited by TheDon; 10-09-2011 at 09:45 PM. |

I took trig and pre calc for fun. Might take calc 1 as well.
The prof for this class is fresh off the boat from china. She trys hard to speak English but it doesn't work well. She also just reads from the slides. So it's an hour of class that I can teach myself sometimes. Her wording on the homework questions is also confusing |

Is there anything in the materials they gave you that further defines the term "wave"? If a wave is always stated as "h(x) = a sin(x)", or something like that, then Kuan's approach looks like a good start. |
