In the complex plane, the number 14 – j5 is located in the

 Neeraj Patel said: (Dec 11, 2010) Because the fourth quadrant is positive. The angle is 19.65 this is positive.

 Chaitanya said: (Dec 25, 2010) I think in 4th quadrant you will get -19.65.

 Rupal said: (Jan 13, 2011) Option D is wright.because r is on x-axis and xl on y-axis.r is (+)and xl is (-).so its possible on 4 th qud.

 Naeem said: (Mar 30, 2012) If we draw the coordinate as taking real value on x-axis and imaginary value on y-axis then the (-j5) will be in -y-axis and real value on +x-axis. Then it is in fourth quadrant.

 Hitesh said: (Aug 18, 2012) Here real value in X axis and imaginari value in Y axis so(+,-) ans is D

 Srikanth said: (Aug 28, 2012) This is in the form of x+jy so x=14 and y=-5 so this is in the fourth quadrant....

 Sidhu said: (Dec 11, 2012) 1 quad= +ve real +ve img 2 quad= -ve real +ve img 3 quad= -ve real -ve img 4 quad= +ve real -ve img This is the reason.

 Dhwani said: (Sep 20, 2013) x axes contains real parts and y axes imaginary. So if we write X+iY then 'X' is real part and 'Y' is imaginary. Similarly the given equation 14-j5 , 14 will be Real part situated on +x axes & -j5 on the negative y axes(4th quadrant).

 Milan Patel said: (Feb 18, 2014) In quadrant co-ordinate is write in form (cos@, sin@). So it also write as cos@+jsin@. So on that the answer will be (cos@, -sin@) so it in fourth quadrant.

 Vamshi said: (Jul 29, 2015) Do we need to convert to polar for answer.

 Raj Kumar said: (Sep 21, 2015) Can you explain please?

 Kiran said: (Feb 3, 2016) I don't know anything. Please anyone explain me?

 Vikas said: (Aug 31, 2016) Nice @Sidhu.

 Fiords said: (Nov 24, 2016) Thanks @Sidhu.

 Sameeksh said: (Sep 14, 2018) The tan inverse(-5/14)=-ve answer. That implies it's in 4th quadrant or 2nd quadrant. But the real coefficient is +ve. So obviously it's in 4th quadrant.
