Step 1
Since we have -2/j, we can multiply both the numerator and the denominator by the conjugate of j, which is -j: (-2/j) * (-j/-j) = (2j)/(-1) = -2j Now, we have the complex number in the form a + bj: 0 - 2j. Show more…

Convert the complex number 5 + 2i into polar form. Express the angle ̄ using degrees over the interval 0° < θ < 360°. You may round the argument to the nearest tenth of a degree (if necessary), but you must express your modulus in its exact form. The value of the modulus or |z| for this complex number is √(5^2 + 2^2). The reference angle (in degrees) formed with the positive x-axis is arctan(2/5). The polar form of the complex number is |z| ∠ θ, where |z| is the modulus and θ is the argument.
