Write the following numbers in the polar form re^iθ
Note:: The horizontal axis is Real
The vertical axis is Imaginary
------
A) 1/5
r = 1/5 θ= pi/2
Point (0,1/5)
y = (1/5)e(i*pi/2)
----------------------------
B) 5 + 5i
r=5sqrt(2) θ= arctan(5/5) = pi/4
Point (5,5)
y = 5*sqrt(2)e^(i*pi/4)
---------------------------
C) 3-3i
Point (3,-3)
r= 3sqrt(2) θ= (7/4)pi
y = 3sqrt(2)*e^(i*(7/4)pi)
========================
