Fifth root of 1 polar form

WebIf you take the square root of both sides, you get x=1. But x=-1 is also valid. Because you're taking the principal square root to get x=1. Same in this case, you would be taking the principal cube root if you would be x=1. but if you think about the non-principal cube roots, either you use the method of this video or you use factorisation. WebSep 16, 2024 · Definition 6.2.1: Polar Form of a Complex Number. Let z = a + bi be a complex number. Then the polar form of z is written as z = reiθ where r = √a2 + b2 and θ is the argument of z. When given z = reiθ, the identity eiθ = cosθ + isinθ will convert z back to standard form. Here we think of eiθ as a short cut for cosθ + isinθ.
