I don't understand how to do this

Hi!
The table above is showing how to plug in a variable to x. For an example,
when x= 4 would equal 17. How we would get this is substitute x with 4 and use our order of operations.
To get 68, we would do this in reverse. We would add 3 to both sides to eliminate the -3 to have a remainder of
Divide both sides by five to solve for x.
We can also check our math and plug in 17/5 into x

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).
