\n" ); document.write( "arctan(tan(t-30)) = arctan(-5)
\n" ); document.write( "t-30 = -78.69 degrees
\n" ); document.write( "theta = = -48.69 deg = 360-48.69 = 311.31 degrees (Answer in QIV)
\n" ); document.write( "OR
\n" ); document.write( "theta = -48.69 degrees or theta = 180-48.69 = 131.31 (Answer in QII)
