Find the argument of the complex number z=1+iv3

elena-14-01-66 [18.8K]

Given:

The complex number is:

$z=1+i\sqrt{3}$

To find:

The argument of the given complex number.

Solution:

If a complex number is $z=x+iy$ , then the argument of the complex number is:

$\theta=\tan^{-1}\dfrac{y}{x}$

We have,

$z=1+i\sqrt{3}$

Here, $x=1$ and $y=\sqrt{3}$ . So, the argument of the given complex number is:

$\theta =\tan^{-1}\dfrac{\sqrt{3}}{1}$

$\theta =\tan^{-1}\sqrt{3}$

$\theta =\tan^{-1}\left(\tan \dfrac{\pi}{3}\right)$

$\theta =\dfrac{\pi}{3}$

Therefore, the argument of the given complex number is $\theta =\dfrac{\pi}{3}$ .

Find the equation of the line using the point-slope formula. Write the final equation using the slope-intercept form. the x-inte

wariber [46]

Step-by-step explanation:

Given x intercept is 1, So (x,y) is (1,0)

When x intercept is 1 then y value is 0

Another point on the line is (-2,3)

Two points are (1,0) and (-2,3)

Find out slope using the two given points

$slope m=\frac{y_{2}-y_1}{x_2-x_1} =\frac{3-0}{-2-1} =-1\\m=-1$

Use point slope formula

m=-1 and point(1,0)

$y-y_{1}=m(x-x_{1})\\y-0=-1(x-1)\\y=-1x+1$

Point slope equation is

$y-0=-1(x-1)$

Equation of the line in slope intercept form is

$y=-1x+1$

Example
from pir^2 ro pi(2r)^2
pi(2r)^2=pi4r^2=4pir^2

basicaly we look for any no options and ones where second is 4 times first
