Find the magnitude and direction angle θ of the following vectors. Round the magnitude to the nearest tenth, and round the direction angle to the nearest degree, if rounding is necessary.
\n" ); document.write( "u = (9, -2)
\n" ); document.write( "----
\n" ); document.write( "magnitude = sqrt[9^2+2^2) = sqrt(85)
\n" ); document.write( "-------------------------------------
\n" ); document.write( "direction angle = arctan(-2/9) = 360-12.53 = 347.47 degrees
\n" ); document.write( "--------------
