Find all solutions of csc x = -2, where 0 ≤ x ≤ 2π. \n" ); document.write( "----- \n" ); document.write( "If csc(x) = -2, sin(x) = 1/csc(x) = -1/2 \n" ); document.write( "------ \n" ); document.write( "If sin = -1/2, the reference angle is pi/6 \n" ); document.write( "------ \n" ); document.write( "Since sin is negative in QIII and QIV \n" ); document.write( "x = pi+(pi/6) = (7/6)pi \n" ); document.write( "or x = (2pi)-(pi/6) = (11/6)pi \n" ); document.write( "------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------- \n" ); document.write( " |
