Leaving Cert Maths - Complex Numbers - Modulus and Argument
In this video I show you how to find the Modulus and the Argument of a Complex Number. You will need this to put a Complex Number in Polar Form and then go on to do De Moivres Theorem.

Leaving Cert Maths - Introduction to Complex Numbers
Просмотров 1,7 тыс.2 года назад
The main thing i should've mentioned at the start is that the sqrt(-1) is represented by 'i'..... this is because the sqrt(-1) is a 'math error' on your calculator so using Imaginary Numbers allows us to deal with negative square roots. For Example Sqrt(-16) is a math error but if we split it up we can say sqrt(16) x sqrt(-1) =(4) x (i) = 4i So essentially, Sqrt(-16) is 4i

    Why do we divide it by 5 at 3:15

    • @mrfitzmaths
      @mrfitzmaths 7 месяцев назад

      Because 5y is equal to 10... But we want what 1y is equal to?... So we divide 5y by 5 to bring it diwn to 1y...qhich shows us that 1y us equal to 2!

    Explain why you “bring this guy across” so kids know why they’re doing it ie. Divide left side by 5 to get rid of the 5, so have to do the same on right side.

    In the state exams if you offer 2 answers, even if one is correct they will give 0 marks as the wrong answer cancels out the correct answer...
