[Solved] Find the cube roots of 125(cos 288 + i sin 288 – Find the cube roots of 125(cos 288° + i sin 288°). Two forces with magnitudes of 25 and 30 pounds act on an object at angles of 10° and 100°, respectively. Find the direction and magnitude of the resultant force. Round to two decimal places in all intermediate steps and in your final answer.What are the cube roots of 125(cos 288 + i sin 288). View the step-by-step solution to: Question What are the cube roots of 125(cos 288° + i sin 288°). Top Answer. Hi. The cube roots are: 4.56-2.03i (principal root)-0.52+4.97i -4.04-2.93i. Explanation: Hello. I calculate the cubic roots of the complex number as I show it in the attached fileThe magnitude is 125, so the magnitude of the cube root is 5. That means the answer will be: z = 5 cos θ + 5i sin θ. Solve for θ using: z³ = 125i. 125 (cos θ + i sin θ)³ = 125 i. Apply DeMoivre/Euler (forgot who did which) on the left to get: 125 (cos 3θ + i sin 3θ) = 125i. cos 3θ + i sin 3θ = i = cos (π/2) + i sin (π/2) That means
