Algebra.Com's Answer #293525 by stanbon(75887) ![]() You can put this solution on YOUR website! How would I go about solving y = 5 sin 2(pi)(x) - 2? So that I can graph it? \n" ); document.write( "------- \n" ); document.write( "You know that a sin curve is normally centered on the origin. \n" ); document.write( "Well move it down so its centered at -2. \n" ); document.write( "---- \n" ); document.write( "You know how the period is normally 2pi. \n" ); document.write( "Find the period for your curve: \n" ); document.write( "Period = (2pi)/b \n" ); document.write( "Your b is (2pi) \n" ); document.write( "So your period is (2pi)/(2pi) = 1 radian \n" ); document.write( "---- \n" ); document.write( "So one cycle of your sin curve starts at x = 0 \n" ); document.write( "and ends at x = 1. It then repeats itself to \n" ); document.write( "the right and to the left. \n" ); document.write( "---------------------------------- \n" ); document.write( "The amplitude is 5 so the curve is centered \n" ); document.write( "at y= -2 and ranges from y = -7 up to y = 3 \n" ); document.write( "----------------------------------- \n" ); document.write( " \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
