1. The problem statement, all variables and given/known data Plot the Following points(given in polar coordinates). Find all the polar coordinates of each point. a. (2, pi/2) b. (2,0) c. (-2, pi/2) d. (-2,0) 2. Relevant equations none 3. 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.
