Solve over [0,360):
\n" ); document.write( "sin^2 theta = cos^2 theta + 1
\n" ); document.write( "-----
\n" ); document.write( "sin^2 = 1-sin^2) + 1
\n" ); document.write( "---------
\n" ); document.write( "2sin^2 = 2
\n" ); document.write( "sin^2 = 1
\n" ); document.write( "sin = +1 or sin = -1
\n" ); document.write( "theta = 90 degrees or theta = 270 degrees
\n" ); document.write( "===========================================
