Solve the equation for solutions in the interval [0, 2 pie): tan squared(2x)-16=0
\n" ); document.write( "tan^2(2x)-16=0
\n" ); document.write( "tan^2(2x)=16
\n" ); document.write( "tan(2x)=±√16
\n" ); document.write( "tan(2x)=±4
\n" ); document.write( "Use inverse tan key on calculator set to radians:
\n" ); document.write( "2x=1.32, 1.82, 4.46, 4.96 radians
\n" ); document.write( "x=0.66, 0.91, 2.23, 2.48 radians \n" ); document.write( "
\n" );
