Just a question about the expression: asinx+bsinx=c=rsin(x+alpha) for this eqn. r= (aa + bb)^1/2 tan-1 x = b/a <<<<<<< is this the same expression for both sine and cos rule? or is it different?

wavelength and if possible amplitude?

How do you read displacement versus time waves? Also im struggling to read the longitudional waves, ie. the dots one. how do you read then?

yep. 10char

constant cutting from one image to another *fuzzing* << confused thoughts? the music. the music changes between each of the personas... from memory thats about all i can think of

cheers for the help. The question ive got is actually jsut worded as a task. "Analyse given text" ALSO nick. would theme be more important than purpose if it was a film that is being studied?

If you were given any text and allowed to study it, then told to write an analysis on it. How would you tackle it? I.e What components would you include in your analysis?

and your point is? i mean assistance doesnt kill ya =]

Cheers for the tips guys I got a scaffold for this question..and it goes into more detail ie Electron Clouds being general across most sorts of bonds it asks for limintations of models for ionic lattices..covalent..etc.

Heres the question: -Chemists have developed models to explain their observations of the world around them. Some of the most useful of these include models of ionic lattices, covalent molecules and covalent and metallic lattices. Discuss the limitations of each of these models. What are...

ah yes trebla. i am yet to know who you are but that seems to be the case =]

thanks a heap

CAn someone prove these for me? (sin 5A)^2 - (sin3A)^2 = sin8Asin2A (1+sin2A)/(1-sin2A)= tan^2 (45+A) tan3x-tanx=2sinx/cos3x For the sake of the world i cant prove them

ok cheers for that Zenger. i shall store that information in general knowledge because i had chosen to do GPS. So what are the latest researches to come about from GPS? Any ideas?

when you look at an image..how do u determine whether its caricature or hyperbole. im in search for images for a poster

5. Electromagnetic waves have potential for future communication technologies and data storage technologies. - identify data sources, gather and process and present information from secondary sources to identify areas of current research and use the available evidence to discuss some of the...

the sources i have show that ghettos were constructed after the invasion of poland began..ie period..1940 april..i have another source stating jews were sent to concentration on feb 1940..does nayone have a valid date for this?
