if x is some angle in degrees and \"0%3C=x%3C=90\", then\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cos(x) = sin(90 - x)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cos(40) = sin(90 - 40)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "cos(40) = sin(50)
\n" ); document.write( "
\n" );
