The basic facts you need to know about
\n" ); document.write( "the sine curve is:
\n" ); document.write( "(1) \"+sin%28x%29+\" repeats itself every \"+2pi+\"
\n" ); document.write( "radians
\n" ); document.write( "(2) the maximum value of \"+sin%28x%29+\" is \"+1+\"
\n" ); document.write( "and this maximum occurs every \"+pi%2F2+%2B-+2pi+\"
\n" ); document.write( "radians
\n" ); document.write( "-----------------------------------------
\n" ); document.write( "(i), (ii), and (iii)
\n" ); document.write( "You are given the interval −π ≤ x ≤ π
\n" ); document.write( "so, the only place where there is a maximum in this
\n" ); document.write( "interval is: \"+x+=+pi%2F2+\"
\n" ); document.write( "------------------------
\n" ); document.write( "Your sine function is \"+3%2Asin%28+x+%29+\", the the maximum is
\n" ); document.write( "\"+3%2A1+=+3+\". Now you know the maximum point is at
\n" ); document.write( "( pi/2, 3 )
\n" ); document.write( "------------------
\n" ); document.write( "The straight line \"+y+=+k%2Ax+\" must also pass through that
\n" ); document.write( "point and also (0,0) since \"+y+=+k%2A0+\" gives you (0,0)
\n" ); document.write( "-------------------
\n" ); document.write( "The slope, \"+k+\", is \"+%28+3+-+0+%29+%2F+%28+pi%2F2+-+0+%29+=+6%2Fpi+\", so the equation is:
\n" ); document.write( "\"+y+=+%28+6%2Fpi%29%2Ax+\"
\n" ); document.write( "-------------------
\n" ); document.write( "Here are plots of
\n" ); document.write( "\"+y+=+3%2Asin%28x%29+\" and
\n" ); document.write( "\"+y+=+%28+6%2Fpi+%29%2Ax+\"\r
\n" ); document.write( "\n" ); document.write( "\"+graph%28+400%2C+800%2C+-pi%2C+pi%2C+-4%2C+4%2C+3%2Asin%28x%29+%2C+%286%2Fpi%29%2Ax+%29+\"
