Find the number of solutions of
\n" ); document.write( "sin theta + 2 cos theta =0
\n" ); document.write( "over the interval [-pi,pi/2].
\n" ); document.write( "----
\n" ); document.write( "Divide thru by cos(t) to get:
\n" ); document.write( "tan(t) + 2 = 0
\n" ); document.write( "tan(t) = -2
\n" ); document.write( "------
\n" ); document.write( "t = arctan(-2) = -1.1070 in QIV
\n" ); document.write( "-----------------
\n" ); document.write( "t = -1.1070+pi = 2.0344 in QII
\n" ); document.write( "------------------------------------
