You can put this solution on YOUR website!
tan x = -1
\n" ); document.write( "tan is negative in the 2nd and 4th quadrant
\n" ); document.write( "Only the 2nd quadrant is in the range
\n" ); document.write( "pi/1< x < 3pi/2
\n" ); document.write( "So, pi - pi/4
\n" ); document.write( "= 3pi/4 (D)
\n" ); document.write( "Hope this helps
\n" ); document.write( ":-)
\n" ); document.write( "
