Question

Plot the point given by the following polar coordinates on the graph below. Each circular grid line is 0.5 units apart.(2, -1)

Answer 1

In polar coordinates we must have two things to plot a point, it's the radius and the angle

If we use a negative angle, it just means that we are doing the rotation clockwise.

Therefore the point (2, -π) is

We do a 2 units long line and rotate is by -π, the result is
