You can put this solution on YOUR website!
great job on both typing formulas in our formula system as well as getting to the solution. You are almost there.\r
\n" ); document.write( "\n" ); document.write( "\"%28x-1%29%5E2%2By%5E2+=+1\"\r
\n" ); document.write( "\n" ); document.write( "that's an equation of a circle with center in point x=1, y=0. \r
\n" ); document.write( "\n" ); document.write( "so, assuming that this is what you want, \"system%28+x=1%2B+cos%28+phi+%29%2C+y=sin%28+phi+%29+%29+\".
\n" ); document.write( "
\n" );
