Write the complex number 1 +i/1 -i into polar form​
IRINA_888 [86]

Answer:

cos(pi/2) + i sin (pi/2)

Step-by-step explanation:

(1+i)/ (1-i)

Multiply top and bottom by (1+i)

(1+i) (1+i)/ (1-i)(1+i)

Foil the top (1+i)(1+i) = 1 +2i +i^2 = 1 +2i -1 = 2i

Foil the bottom ( 1+i)(1-i) = 1 - i^2 = 1 - (-1) =2

2i/2 = i

the magnitude is (0^2+1^2) = 1

The angle is tan^-1( 1/0) = pi/2

cos(pi/2) + i sin (pi/2)

I need help like RN!!!<br> what are the foci of the ellipse? graph the ellipse. 18x^2+36y^=648
Thepotemich [5.8K]
Hi,

18x^2+36y^2=648\\&#10;&#10;\Rightarrow ( \dfrac{x}{6})^2+( \dfrac{y}{3* \sqrt{2} } )^2=1\\&#10;&#10;a=6,\ b=3* \sqrt{2}\\&#10;&#10;c= \sqrt{a^2-b^2} = \sqrt{36-18} =3* \sqrt{2}\\&#10;&#10;
Center is (0,0)
Foci are (-3√2,0) and (3√2,0)
