Use a sum or difference formula to find the exact value of the following.
\n" ); document.write( "sin(190°)cos(10°)-cos(190°)sin(10°)=
\n" ); document.write( "-----------------------
\n" ); document.write( "sin(190) = sin(180+10) = sin(180)cos(10)+cos(180)sin(10) = 0-sin(10)
\n" ); document.write( "-------------------------
\n" ); document.write( "cos(190) = cos(180+10) = cos(180)cos(10)-sin(180)sin(10) = -cos(10)-0
\n" ); document.write( "------------------------------------------
\n" ); document.write( "Put those values in for sin(190) and cos(190) to get:
\n" ); document.write( "= (-sin(10)(cos(10)) -(-cos(10))(sin(10))
\n" ); document.write( "-----
\n" ); document.write( "= 0
\n" ); document.write( "====================
