The adjacent side is $\"+1+\"$
\n" ); document.write( "The rotating vector is $\"+2+\"$
\n" ); document.write( "The opposite side is $\"+sqrt%283%29+\"$ ,
\n" ); document.write( "so $\"+theta+=+60+\"$ degrees
\n" ); document.write( "and $\"+theta+=+pi%2F3+\"$
\n" ); document.write( "This is with $\"+theta+\"$ in the 1st quadrant
\n" ); document.write( "--------------------------------------
\n" ); document.write( " $\"+theta+\"$ could also be in the 4th quadrant
\n" ); document.write( "The adjacent side is $\"+1+\"$
\n" ); document.write( "The rotating vector is $\"+2+\"$
\n" ); document.write( "The opposite side is $\"+-sqrt%283%29+\"$ ,
\n" ); document.write( " $\"+theta+=+300+\"$ degrees
\n" ); document.write( "and $\"+theta+=+%28+5%2Api+%29+%2F+3+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "In the the other 2 quadrants, 2nd and 3rd,
\n" ); document.write( "the cos is negative\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
