| Algebra.Com's Answer #320654 by lwsshak3(11628)      You can put this solution on YOUR website! cos (theta-(3pi/4)) \n" ); document.write( ".. \n" ); document.write( "What you have here is a cosine function of the form: y=Acos(Bx-C) with A=amplitude, period=2π/B, and phase shift=C/B \n" ); document.write( "For given cosine function, y=cos(x-3π/4) \n" ); document.write( "Amplitude=1 \n" ); document.write( "B=1 \n" ); document.write( "Period=2π/1=2π \n" ); document.write( "Phase shift=3π/4 to the right \n" ); document.write( "Ans: \n" ); document.write( "What you have here is a cosine function whose value varies from +1 to -1 over one period(2π), depending on what theta(x) is. \n" ); document.write( " |
