document.write( "Question 923952: T-table for graphing sine/cosine graph? I understand most of this image. I have to do this without a calculator that's why I have to set this up with a t-table. From the image I just need to know where to 4π/4 comes from and why the phase shift goes from π/2 to 2π/4 I understand the rest it's just those two parts that make no sense to me. \r

You can put this solution on YOUR website!
you have \"y=sin%282x-pi%29\"\r
\n" ); document.write( "\n" ); document.write( "\"y+=+a+sin%28bx+%2B+c%29\"=> in your case \"a=1\",\"b=2\", and \"c=-pi\"\r
\n" ); document.write( "\n" ); document.write( "Both \"b\" and \"c\" in these graphs affect the phase shift (or displacement), given by:\r
\n" ); document.write( "\n" ); document.write( " \"Phase_+shift=%28-c%29%2Fb\" => in your case \"%28-%28-pi%29%2F2%29=pi%2F2\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can write \"pi%29\" as \"4pi%2F4%29\" or \"2pi%2F2\", and that was used because \"x\" values\r
\n" ); document.write( "\n" ); document.write( "The choice of the values of \"x\" in the table correspond to \"x\" and \"y\" intercepts, maxima and minima points.\r
\n" ); document.write( "\n" ); document.write( "\"x\"|\"y\"
