Yesterday in class, we learned how to find arc length in polar. To find polar arc length, we learned an equation that was similar to the one used to find the arc length in parametric equations. We also learned that when dr/d theta is positive, the distance from the pole is increasing, and when it is negative, the distance from the pole is decreasing.
