Let z = 4(cos 135° + i sin 135°) and w = 3(cos 45° + i sin 45°). Write the rectangular form of zw.
\n" ); document.write( "---------------------
\n" ); document.write( "zw = 12cis(135+45) = 12cis(180)
\n" ); document.write( "zw = 12cos(180) = 12i*sin(180)
\n" ); document.write( "zw = -12 \n" ); document.write( "

\n" );
