Solve this equation graphically on the interval [0, 2π]. Sketch the graph and list the solutions.
\n" ); document.write( "sin x – 1 = cos x
\n" ); document.write( "-------------------
\n" ); document.write( "Says to solve it graphically.
\n" ); document.write( "y = sin(x) - cos(x) - 1
\n" ); document.write( "--
