You can put this solution on YOUR website!
1. find the value of x and y in:
\n" ); document.write( "x+(y-6)i=5+9i
\n" ); document.write( "The real parts are equal x = 5
\n" ); document.write( "----
\n" ); document.write( "y-6 = 9
\n" ); document.write( "===========
\n" ); document.write( "2. find the two square roots of -i
\n" ); document.write( "r = 1
\n" ); document.write( "Angle t = 270 degs
\n" ); document.write( "--> 1cis(270)
\n" ); document.write( "sqrt = 1cis(135) & 1cis(315)
\n" ); document.write( "1cis(135) = 1cos(135) + isin(135)
\n" ); document.write( "= \"%28sqrt%282%29%2F2%29%2A%28-1+%2B+i%29\"
\n" ); document.write( "= \"%28sqrt%282%29%2F2%29%2A%281+-+i%29\"
\n" ); document.write( "
\n" );
