Tutorial on complex numbers and complex conjugates

[saad]

Been two years in university and had to go search online to remember some complex number stuff. Hearing your voice again gave me a smile :)

Thank you SO much! I really hope to meet you someday..you're a great inspiration for me :)))

[mydailysilence]

thank you so much for every tutorial! it helps me so much and I love you!

If you mean the complex conjugate is e^(-ipi/4) then e^(ipi/4) multiplied by e^(-ipi/4) will give e^0 = 1

[S..S]

what if we had an exponential like e^(ipi/4) will that make e^(-ipi/4) ?? and will they cancel each other out as well ???

Salam, i need help with the properties of complex no.s and conjugates. Can you suggest some video? i can't find it anywhere.

[ExamSolutions_Maths]

No, I assume you are talking about 5i multiplied by -5i? -5 multiplied with 5 gives -25 but i^2 gives -1 so -25 multiplied by -1 gives 25.

I suppose its ok to use x+iy for Z and for bar Z x-iy?

[S..S]

oh ok what if they are added together so
e^(ipi/4)+e^(-ipi/4)

Conjugate is nothing, but image of complex number represented on graph,
