I have to write a two page paper and a 10 min presentation on trigonometry and radios and I can't find anything! I know it has something to do with sin and cos but I can find nothing to elaborate on. I don't really know anything about sin and cos! Can anyone help me? Basically I need to know what the relationship between trig and radios are but anything on sin and cos will help! :)

Are you sure it's not supposed to be "triangulation"?

It may be that you're searching the wrong word. Trigonometry is all about ratios, not radios.

Here are the basics from which you can certainly get enough to do a decent 2 page paper and 10 minute presentation:

... oops, I see Need beat me to the punch...

Look close at the actual assignment to confirm exactly what it is you need to present on.

My teacher said do a paper on trig and radios. I just started this class so I am not sure about anything. I'm not sure

Then you'd better go back and get the correct info about the paper/presentation.

The one thing I am sure of is that it's not radios: It's ratios.

This was my angle: http://searchnetworking.techtarget.c...753924,00.html
"Triangulation is a process by which the location of a radio transmitter can be determined by measuring either the radial distance, or the direction, of the received signal from two or three different points. Triangulation is sometimes used in cellular communications to pinpoint the geographic position of a user."

Npe it says radios not ratios I hope it did say ratios it would be a lot easier. Thanks

That might be it I might have to explain how trig helps explain radios! thanks

Good eye, Need!

Tahmena, I apologize, and stand corrected then.

... where's the smilie with mud on his face? :o

Its oki thanks for replying anyway it made me double check

You can connect the two by using radio frequency which is expressed using sine functions. Maybe you can read more from this http://fas.org/man/dod-101/navy/docs/es310/FM.htm

What is the course on? If it is a pure trigonometry course I imagine that you've just got a typo. How about you check it with your teacher? This would also be a good time to clear up any other problems you are having (you said you didn't really follow what is going on).

Hi, Tah,
You said "I don't know anything about sin and cos".
I second the answer before mine about checking with your teacher. If you don't know the equations for sin and cos, or anything about them, doing some "cramming" on what they are will be critical to presenting anything about them, or writing a paper.
Best of luck.
