Prove:
\n" ); document.write( "(sec^2x -1) / (sec^2x)= sin^2x
\n" ); document.write( " $\"%28sec%5E2%28x%29-1%29%2Fsec%5E2%28x%29=sin%5E2%28x%29\"$
\n" ); document.write( "start with left side:
\n" ); document.write( " $\"%28sec%5E2%28x%29-1%29%2Fsec%5E2%28x%29\"$
\n" ); document.write( "..
\n" ); document.write( " $\"%28tan%5E2%28x%29%29%2Fsec%5E2%28x%29\"$
\n" ); document.write( "..
\n" ); document.write( " $\"%28sin%5E2%28x%29%2Fcos%5E2%28x%29%29%2F%281%2Fcos%5E2%28x%29%29=sin%5E2%28x%29\"$
\n" ); document.write( "verified:left side=right side \n" ); document.write( "

\n" );
