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).

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.

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.

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.

Converting it to the polar form, the polar angle would be (-)19.65 which is equal to 340.35 as you rotate clockwise. Thus, it lie in Q4.

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.
2 quad= -ve real +ve img
3 quad= -ve real -ve img
4 quad= +ve real -ve img
This is the reason.

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.

This is in the form of x+jy so x=14 and y=-5 so this is in the fourth quadrant....

Because the fourth quadrant is positive. The angle is 19.65 this is positive.
