Complex Numbers In Polar Form - De Moivre's Theorem
Added 2023-01-04 03:15:04 +0000 UTCThis precalculus video tutorial focuses on complex numbers in polar form and de moivre's theorem. It explains how to find the products, quotients, powers and nth roots of complex numbers in polar form as well as converting it to and from rectangular form. This video contains plenty of examples and practice problems and is useful for high school and college students taking precalculus or trigonometry.

b^2 is 4^2. The b does not include 'i'. In a+bi standard form, the b is separate from the i.

2024-11-27 22:26:14 +0000 UTCat 12:10 it says that the imaginary part (4i) squared, is 4x4. But we learned previously that "i" squared is "-1". You do not mention the "-1". How do we know when to use -1 for imaginary part and when not to? please advise?
