WebSubstitute 0, 1, and 2 for k into equation (2) and simplify the resulting equations to obtain the required roots as shown below. Denote the roots as z 0, z 1, and z 3 for k=0,1, and 2 respectively. z 0 = 3 cos 240 ° + 360 ° 0 3 + i sin 240 ° + 360 ° 0 3 = 3 cos 240 ° 3 + i sin 240 ° 3 = 3 cos 80 ∘ + i sin 80 ∘ = 3 c i s 80 ∘

WebIt is easy to work out the cube root of a perfect cube, but it is really hard to work out other cube roots. Example: what is the cube root of 30? Well, 3 × 3 × 3 = 27 and 4 × 4 × 4 = 64, so we can guess the answer is between 3 and 4. WebCube Root of 400 by Halley's Method Its formula is ∛a ≈ x ( (x 3 + 2a)/ (2x 3 + a)) where, a = number whose cube root is being calculated x = integer guess of its cube root. Here a = 400 Let us assume x as 7 [∵ 7 3 = 343 and 343 is the nearest perfect cube that is less than 400] ⇒ x = 7 Therefore, ∛400 = 7 (7 3 + 2 × 400)/ (2 × 7 3 + 400)) = 7.37 simple painting using coffee
