Question

Представить в алгебраической формуле числа:z=(cos2π+isin2π)очень нужно, прошу

Answer 1

Π-это 180°
2π-это 2*180=360°
sin(2π)=0
cos(2π)=1
z=1+0=1
ответ
z=1

Answer 2

Algebraic Representation of a Complex Number

To represent the complex number in algebraic form, we can use Euler's formula, which states that for any real number θ:

e^(iθ) = cos(θ) + i*sin(θ)

Here, z = cos(2π) + i*sin(2π). Using Euler's formula, we can express this as:

z = e^(i*2π)

This representation allows us to express the complex number in terms of the exponential function raised to the power of an imaginary number.
