If \"+s+\" is the plane's speed in mi/hr then
\n" ); document.write( "\"+s%2Acos%2835%29+\" is the horizontal component of the speed in mi/hr
\n" ); document.write( "\"+s%2Acos%2835%29+=+70+\" mi/hr
\n" ); document.write( "\"+s+=+70+%2F+cos%2835%29+\"
\n" ); document.write( "\"+s+=+70+%2F+.81915+\"
\n" ); document.write( "\"+s+=+85.454+\" mi/hr
\n" ); document.write( "
\n" );
