so that would be sqrt(5) L3.32145... could you take a look at the original problem and tell me if I am right...(1+2j)^2/(1-2j) they wanted the solution in polar.

thanks i just wasnt sure about the angle, my calculator says it should be 0.1799, probably co-terminal or in a different quadrant or something?

Different quadrant - third quadrant. If you used arctan, you'll get an angle in the first or fourth quadrant.
 

FAQ: Divide Polar Form: Solve 5∠2.214/√5∠-1.107

What does "Divide Polar Form" mean?

"Divide Polar Form" refers to the process of dividing two complex numbers expressed in their polar form, which consists of a magnitude (represented by the number before the angle symbol) and an angle (represented by the number after the angle symbol).

What is the significance of the numbers in the given expression, 5∠2.214/√5∠-1.107?

The number before the angle symbol (2.214) represents the magnitude or distance from the origin of the complex number, while the number after the angle symbol (-1.107) represents the angle or direction of the complex number in radians. The square root symbol (√) indicates that the number following it is the square root of the number before it.

How do you divide two complex numbers in polar form?

To divide two complex numbers in polar form, you must first convert them into rectangular form, then perform the division using the formula (a+bi)/(c+di) = [(ac+bd)/(c^2+d^2)] + [(bc-ad)/(c^2+d^2)]i. After obtaining the result in rectangular form, you can convert it back to polar form by using the formula r = √(a^2+b^2) and θ = tan^-1 (b/a).

What is the result of dividing 5∠2.214 by √5∠-1.107?

The result of dividing 5∠2.214 by √5∠-1.107 is approximately 3.162∠3.321.

How can the division of complex numbers in polar form be useful in real life?

The division of complex numbers in polar form can be useful in analyzing alternating currents in electrical engineering, modeling wave propagation in physics, and solving problems in navigation and surveying that involve direction and distance.
