If $\"sin%28theta%29+=+-2%2F7\"$ , what are the possible coordinates for point \"P?\" What are the values of $\"cos%28theta%29\"$ and $\"tan%28theta%29\"$ ?
\n" ); document.write( "-----------
\n" ); document.write( "cos = sqrt(1 - sin^2) = sqrt(45/49) = 3sqrt(5)/7
\n" ); document.write( "cos may be + or minus, the quadrant is not given
\n" ); document.write( "tan = sin/cos = -2/(3sqrt(5)) = -2sqrt(5)/15 (sign not known)
\n" ); document.write( "==============
\n" ); document.write( "Where is point P? \n" ); document.write( "

\n" );
