Question

Which set of polar coordinates describes the same location as the rectangular coordinates (0,-2)

Answer 1

the relation between polar coordinate n cartesian coordinate is

\[r = \sqrt{{x^2 + y^2}}\]

Answer 2

r = sqrt(x^2 + y^2)
r = sqrt((0)^2 + (-2)^2).... solve for "r" here...


and then use the relation... tan teeta = y/x...
