You can put this solution on YOUR website!
arcsin(cos(pi/3) = ?????
\n" ); document.write( "pi/3 is equivalent to 60 degrees because pi/3 radians * 180/pi = 180/3 = 60 degrees.
\n" ); document.write( "cos(60) = 1/2.
\n" ); document.write( "arcsin(1/2) = 30 degrees.
\n" ); document.write( "30 degrees * pi / 180 = pi/6.
\n" ); document.write( "arcsin(cos(pi/3) = pi/6.\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
