The point (-3,-3) is in the third quadrant.
\n" ); document.write( "We know that \"r=sqrt%28x%5E2%2By%5E2%29\" ,
\n" ); document.write( "and in this case that would be
\n" ); document.write( "\"r=sqrt%28%28-3%29%5E2%2B%28-3%29%5E2%29=sqrt%282%2A3%5E2%29=highlight%283sqrt%282%29%29\" .
\n" ); document.write( "We also know that ,
\n" ); document.write( "so there are two angles in \"0%3C=theta%3C2pi\"
\n" ); document.write( "that have \"tan%28theta%29=1\" .
