Question
Explain why the point with polar coordinates (0,0) is an intersection point of the curves $r=\cos \theta$ and $r=\sin \theta$ even though $\cos \theta \neq \sin \theta$ when $\theta=0$.
Step 1
In polar coordinates, the first number represents the distance from the origin (r), and the second number represents the angle from the positive x-axis (θ). So, the point (0,0) means that the point is at the origin. Show more…
