Explanation Given information: The given number is − 1 . Formula used: Demoivre’s Theorem: Let z = r ( cos θ + i sin θ ) be a complex number in polar form. If n is a positive integer, then z to the n t h power, z n is z n = [ r ( cos θ + i sin θ ) ] n = r n ( cos n θ + i sin n θ ) w h e r e n = 0 , ± 1 , ± 2 , ... Polar form of z = x + i y is z = r ( cos θ + i sin θ ) Where r = x 2 + y 2 a n d θ = π − tan − 1 | y x | . sin x and cos x are periodic function with period 2 n π so sin x = sin ( 2 n π + x ) , cos x = cos ( 2 n π + x ) . Calculation: z 4 = 0 − i ------(1) [Given] In above equation x = -1 and y = 0 so r = x 2 + y 2 = ( − 1 ) 2 + 0 = 1 a n d θ = π − tan − 1 | y x | = π − tan − 1 | − 0 1 | = π − tan − 1 ( 0 ) = π − 0 = π Polar form of above equation (1) is z 6 = cos π + i sin π ------(2) Since sinx and cosx are periodic function, so we can write equation (2) z 6 = cos ( 2 n π + π ) + i sin ( 2 n π + π ) Now take the sixth root of both sides z = [ cos ( 2 n π + π ) + i sin ( 2 n π + π ) ] 1 6 z = [ cos ( 2 n π + π 6 ) + i sin ( 2 n π + π 6 )

Directions: Set your calculators on radians at this point. Do not round off during intermediate solutions. Use 3 decimal places (if applicable) in your final answer. For complex numbers, use this format (a+jb): 1. No spaces in between! 2. Use 'j' as the imaginary number 3. Use 3 decimal places (if applicable) for Real and Imaginary parts. Ex. 1.247+j0.557, 1.5-j0.5 Calculate the 3-point DFT of the given sequence: x(n) = [10 -1]

Write the complex number in polar form. Express the argument in radians, in terms of pi. z=-1-i
