Question

Plot the point that has the given polar coordinates. Give two other polar coordinate representations of the point, one with r < 0 and one with r > 0

Point ===> (1,5pi/4)

I got the larger r-value which is (1,pi/4).

How do I get the smaller r-value?

Answer 1

r = radius i thought

Answer 2

the r<0 is just negating the radius when you re 180 degrees off
