    Thanks for the video! Clear and concise. Also, for those that are curious about the formula, it is pretty simple to derive when you represent the complex number in exponential form:
    Let A = magnitude of a complex number, and theta = phase of the complex number:
    sqrt( A * exp(j * theta) )
    => (A * exp(j * theta))^(1/2)
    Using the laws of exponents to simplify:
    => A^(1/2) * exp(j * theta / 2)
    => sqrt(A) * exp(j * theta / 2)
    Converting back to phasor form yields:
    sqrt(A) ∠ (theta/2)
    I like exponential notation in this case because it is easier to work with than rectangular notation, which can save you time on exams.

    Hello thank for this, I have a question, how about if its for cuberoot? Do I divide it by 3? And divide by 4 if rooted to 4?

    • @tooirrational
      @tooirrational  2 роки тому +3

      I am glad you liked it...yes you can divide by 3 for cube root and 4 for root 4 but that will give only 1 solution out of 3 in cube root and 4 in 4th root...for others you will have to add 2n pi to the original angles and divide by 3 or 4 to get different angles

    may i askk? why the angle is being divided by 2 ?

    • @tooirrational
      @tooirrational  Рік тому +1

      because we are taking square root...if it was cue root we would divide by 3

    Hello what if the complex number is raised by 3/2?

    • @tooirrational
      @tooirrational  7 місяців тому +1

      You can cube it first and then find the root

    Please please please make a video how to find square root of a complex number using FX 991cw calculator

    • @tooirrational
      @tooirrational  8 місяців тому

      You can calculate the same things in 9991cw as well...just search for 991cw complex numbers and you will understand the standard functions and then apply the same method
