Express the equation cot 1 − 2 tan 1 = sin 21 in the form a cos4
\n" ); document.write( "1 + b cos2
\n" ); document.write( "1 + c = 0, where a, b
\n" ); document.write( "and c are constants to be determined.
\n" ); document.write( "

\r\n" );
document.write( "Does cot 1 and tan 1 mean cot(1°) and tan(1°) or cot(1 radian) and tan(1 radian).\r\n" );
document.write( "Either way, there is no way it can equal to sin(21), so there is no way we can\r\n" );
document.write( "help you because what's written here makes no sense mathematically.  Sorry.\r\n" );
