Question

STATEMENT OF

DEMOIVRE THEORAM​

Answer 1

Answer:

hii

Step-by-step explanation:

In mathematics, de Moivre's formula states that for any real number x and integer n it holds that where i is the imaginary unit. The formula is named after Abraham de Moivre, although he never stated it in his works. The expression cos(x) + i sin(x) is sometimes abbreviated to cis(x).

Answer 2

complex number is made up of both real and imaginary components. It can be represented by an expression of the form (a+bi), where a and b are real numbers and i is imaginary. When defining i we say that i = √(-1). Along with being able to be represented as a point (a,b) on a graph, a complex number z = a+bi can also be represented in polar form as written below:

z = r (cos θ + i sinθ)

where r = [z] = √(a2 + b2)

and

θ = tan-1(b/a) or θ = arctan(b/a)

and we also have: a = r cosθ and b = r sinθ

hope it's help you...
