Well -i is cis(-pi/2), so it rotates by pi/2 clockwise.Isn't 5: A since a rotation by -i is a rotation pi/4 clockwise?
No B is correct because if you rationalise the complex number given you get -i which is a rotation of 90 degrees towards the right, hence clockwise. Hence B is correctIsn't 5: A since a rotation by -i is a rotation pi/4 clockwise?
For Question 2, option (A) doesn't satisfy p'(1) = 0. Remember, to be a multiple root, we also need p'(1) = 0.Can you explain 7? And I thought 2 was A. Agree with the rest
Remember, the constant terms disappear when we differentiate.Correct me if I'm wrong but I am pretty sure for A P'(1) = 0 and for C P'(1) = 1
