What are the x's of: (sec)x = (cos)x
\n" ); document.write( "x=acute angle
\n" ); document.write( " $\"sec%28x%29=cos%28x%29\"$
\n" ); document.write( " $\"1%2Fcos%28x%29=cos%28x%29\"$
\n" ); document.write( " $\"1=cos%5E2%28x%29\"$
\n" ); document.write( "cos(x)=1
\n" ); document.write( "x=0 \n" ); document.write( "

\n" );
