3-3i
\n" ); document.write( "r=sqrt(3^2+(-3)^2)=3 sqrt(2)
\n" ); document.write( "tan theta=-3/3=-1
\n" ); document.write( "graph of function is in fourth quadrant, (3 is on horiz axis and -3 on the vertical axis) so theta is 7 pi/4
\n" ); document.write( "3 sqrt(2)[cos (7 pi/4)+ sin(7 pi/4)]
\n" ); document.write( "
\n" );
