Algebra.Com's Answer #459616 by Cromlix(4381)![]() ![]() 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( " |
