thank you sir make more videos on numericals
sir, Z1 negative x-axis par bhi toh lie kar sakta tha?? last question me...
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.
but that will change the answer ....
