How to solve this eqaction
\n" ); document.write( "Solve the equation 7cosx + 3 = 0 over the interval ( 0,360)
\n" ); document.write( "--------
\n" ); document.write( "cos(x) = -3/7
\n" ); document.write( "-------
\n" ); document.write( "x = arccos(-3/7) = 115.38 degrees
\n" ); document.write( "Also
\n" ); document.write( "180-115.38 = 64.62
\n" ); document.write( "x = 180+64.62 = 244.62 degrees
\n" ); document.write( "============
