For a pair of sample x and y values, the residual exists as the distinction between the observed sample value of y and the y value that exists indicated by utilizing the regression equation.

<h3>What is the difference between the observed sample value of Y and the Y value that exists as predicted by utilizing the regression equation?</h3>

In regression analysis, the distinction between the observed value of the dependent variable and the predicted value exists named the residual.

A regression equation exists utilized in stats to estimate what relationship if any, exists between sets of data.

For a pair of sample x and y values, the residual exists as the distinction between the observed sample value of y and the y value that exists indicated by utilizing the regression equation.

Residual = observed y - predicted y.

From Euler’s relation eiθ = cosθ + isinθ,
adelina 88 [10]

Answer:

(a) The graphic representation is in the attached figure.

(b) \cos(\theta) = \frac{e^{i\theta} + e^{-i\theta}}{2}.

(c) \sin(\theta) = \frac{e^{i\theta} - e^{-i\theta}}{2i}.

Step-by-step explanation:

(a) Given a complex number e^{i\theta} we know, from Euler's formula that e^{i\theta} = \cos(\theta)+i\sin(\theta). So, it is not difficult to notice that

|e^{i\theta}|^2 = \cos^2(\theta)+\sin^2(\theta) =1

so it is on the unit circumference. Also, notice that the Cartesian representation of the complex number is (\cos(\theta), \sin(\theta)).

Now,

e^{-i\theta} = \cos(\theta)+i\sin(-\theta) = \cos(\theta)-i\sin(\theta).

Notice that e^{-i\theta} has the same modulus that e^{i\theta}, so it is on the unit circumference. Beside, its Cartesian representation is (\cos(\theta), -\sin(\theta)).

So, the points (\cos(\theta), \sin(\theta)) and (\cos(\theta), -\sin(\theta)) are symmetric with respect to the X-axis. All this can be checked in the attached figure.

(b) Notice that

e^{i\theta} + e^{-i\theta} = \cos(\theta)+i\sin(\theta) + \cos(\theta)-i\sin(\theta) = 2\cos(\theta)

Then,

\cos(\theta) = \frac{e^{i\theta} + e^{-i\theta}}{2}.

(c) Notice that

e^{i\theta} - e^{-i\theta} = \cos(\theta)+i\sin(\theta) - \cos(\theta)+i\sin(\theta) = 2i\sin(\theta)

Then,

\sin(\theta) = \frac{e^{i\theta} - e^{-i\theta}}{2i}.
