Sir.. I have a question... Plz do reply...
Well, in the last question, I got the concept of placing the roots symmetrically and all the roots having distance 2pi/n
But sir can we interchange the roots...?
I mean z1, z2 & z5 (For - ve z) is taken on the x axis, 1st Quadrant & 4th Quadrant respectively... So can we interchange them with z3 & z5
I mean z3 in 1st quad. Z4 in 4th quad. Z1 on -ve x axis z2 in 2nd quad. & z5 in 3rd quad.
