You can put this solution on YOUR website!
a) Since $\"+x=r%2Acos%28theta%29\"$ and $\"y=r%2Asin%28theta%29\"$ , we have $\"x=3%2Acos%285%2Api%2F6%29=3%2A%28-sqrt%283%29%2F2%29=%28-3%2Asqrt%283%29%29%2F2\"$ and $\"y=3%2Asin%285%2Api%2F6%29=3%2A1%2F2=3%2F2\"$ . So the coordinates are $\"%28-%283%2Asqrt%283%29%29%2F2%29\"$ , $\"3%2F2\"$ .
\n" ); document.write( "b) $\"x=cos%28pi%2F2%29=0\"$ $\"y=sin%28pi%2F2%29=1\"$ The coordinates are (0,1).
\n" ); document.write( "c) $\"x=3%2Acos%2811%2Api%2F18%29\"$ , $\"y=3%2Asin%2811%2Api%2F18%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
