15(pi/4) is a multiple of pi/4.
\n" ); document.write( "remember a unit circle is 2pi. In this case, 8pi/4 = 2pi.
\n" ); document.write( "15-8 =7, so we really have
\n" ); document.write( "7pi/4.
\n" ); document.write( "every pi/4 = 45 degrees, so
\n" ); document.write( "7*45 = 315 degrees. This is a 45 degree angle in quad IV
\n" ); document.write( "--
\n" ); document.write( "34pi/3 is multiple of pi/3.
\n" ); document.write( "remember a unit circle is 2pi . In this case, 6pi/3 = 2pi
\n" ); document.write( "34pi/3-6pi/3-6pi/3-6pi/3-6pi/3-6pi/3 = 4pi/3.
\n" ); document.write( "every pi/3 is 60 degrees, so
\n" ); document.write( "4*60 = 240, or a 60 degree angle into quad III. \n" ); document.write( "

\n" );
