a. (2, pi/2)
b. (2,0)
c. (-2, pi/2)
d. (-2,0)
Homework Equations
none
The Attempt at a Solution
I have plotted it on a graph but could someone explain to me how this answer is correct for a.?
(2, pi/2 + 2npi) and (-2, pi/2 + (2n + 1)pi)
where n is any integer.
So what I have is there is a point on the positive x-axis on 2. An angle pi/2 since r=2 and theta = pi/2.
The ray passes down from the positive y-axis to the negative y-axis. So the angle from the initial ray to the end of the ray on the negative y-axis is 3pi/2.
*Sorry I didn't use Latex, I figured it out after finishing typing out the question.
