What are the solutions to x3=5−5i in polar form

asambeis [7]

Answer:

$z_1=(5\sqrt{2})^{1/3}cis(\frac{7\pi}{12})$

Step-by-step explanation:

To find the roots of the complex number you use the following formula:

$z=re^{i\theta}\\\\z_k= (r)^{1/n}[cos(\frac{\theta+2\pi k}{n})+sin(\frac{\theta+2\pi k}{n})];\ \ k=0,1,2..n-1$ (1)

in this case the polar number in polar form is:

$r=\sqrt{5^2+5^2}=5\sqrt{2}\\\\\theta=tan^{-1}(\frac{-5}{5})=-45\°$

By replacing in (1) you obtain:

$z_0=(5\sqrt{2})^{1/3}cis(\frac{-\pi/4+0}{3})\\\\z_1=(5\sqrt{2})^{1/3}cis(\frac{-\pi/4+2\pi}{3})=(5\sqrt{2})^{1/3}cis(\frac{7\pi}{12})\\\\z_2=(5\sqrt{2})^{1/3}cis(\frac{-\pi/4+4\pi}{3})=(5\sqrt{2})^{1/3}cis(\frac{15\pi}{12})$

hence, you have:

You will add numbers that are relevant to your life and then find the square root of that sum in simplified radical form. Find t

marishachu [46]

Step-by-step explanation:

A. Dad = 50, Mum = 47, Sister = 22

me = 19

Total Sum = 50 + 47 + 22 + 19

= 136

√136 = 11.662.

B. + 1435 797 202 = 40

√40 = 6.33

C. BRYAN = 2 + 18 + 25 + 14 = 59

√59 = 7.68.

Identify the first 4 terms in the arithmetic sequence given by the explicit formula ƒ(n) = 8 + 3(n – 1).

alexandr402 [8]

Answer:

Step-by-step explanation:

f(n) = 8 + 3(n) - 3

f(n) = 5 + 3n

f(1) = 5 + 3(1)

f(1) = 8

f(2) = 5 + 3(2)

f(2) = 5 + 6

f(2) = 11

f(3) = 5 + 3*3

f(3) = 14

f(4) = 5 + 3*4

f(4) = 17
