Answer: the answer is 13
Step-by-step explanation:
Mean means to find the average so add them all and divide by 4.
The subtraction of complex numbers
is cos(π)+i sin(π).
Given
[cos(3π/4+i sin(3π/4) and
=cos (π/2) +i sin(π/2)
We have to find the value of
.
A complex number is a number that includes real number as well as a imaginary unit in which
. It looks like a+ bi.
We have to first solve
and then we will be able to find the difference.

[ cos (3π/4)+i sin (3π/4)]
[cos(π-π/4)+ i sin (π-π/4)]
=
[-cos(π/4)+sin (π/4)]
=
(-1/
+1/
)
=
=0
cos(π/2)+i sin (π/2)
=0+i*1
=1
Now putting the values of
,

=-1
=-1+i*0
=cos (π)+i sin(π)
Hence the value of difference between
is cos(π)+i sin(π).
