WebMar 7, 2024 · To show the theorem is also true for negative integers, we just. = cos (-nx) + i sin (-nx). So DeMoivre's Theorem is true for all integers, positive and negative. functions … WebDe Moivre's formula proves that the power of a complex number in a polar form is similar to raising the modulus to the same power & then multiplying the argument with the same power accordingly. For example: For real numbers; It is written as, (cos x + I sin x) n = cos (nx) + I sin (nx) Or. (e iθ) n = e inθ. n= positive integer.

WebThe following is true for any real integer x: [Mathematical Statement] (cos x + i sin x)n = cos (nx) + isin (nx) OR Where ” n ” is a positive integer, ” i” is the imaginary portion, and i = √-1 Also assume i2 = -1. Remark: The result may be proved to be true even if n is even when n is a negative integer. n is what’s known as a rational number.
