\n" ); document.write( "Write a sinusoidal curve for each in the form.
\n" ); document.write( "Describe how you arrived at your equation.
\n" ); document.write( "How well did your equation fit the data?
\n" ); document.write( "----------
\n" ); document.write( "You know the sin usually ranges from -1 to +1.
\n" ); document.write( "You data ranges from 314 to 319.9
\n" ); document.write( "The difference is 5.9
\n" ); document.write( "Half of that is 2.95
\n" ); document.write( "That is the amplitude of your sin curve.
\n" ); document.write( "EQUATION: y=2.95
\n" ); document.write( "--------
\n" ); document.write( "You also know the center of y=sinx i2 zero.
\n" ); document.write( "Your middle value is 314+2.95=316.95
\n" ); document.write( "Your equation looks like y=2.95sinx + 316.95
\n" ); document.write( "----------
\n" ); document.write( "If you have a graphing calculator put that in and
\n" ); document.write( "graph it. Check the TABLE to see what y-values
\n" ); document.write( "you get with x=1,2,3, etc.
