Students learn what arcs and central angles are. Students learn to set up a proportion to...
1. Find arc length when given the radius and measure of the central angle that intercepts the arc.
2. Find the measure of the central angle when given the radius and arc length.
3. Find the radius when give

When teaching graphing polar equations, I recommend breaking it up based upon type of graph related. One of the more difficult topics for students is roses, specifically using symmetry to graph coordinates so they don't need to make a table for all values. After teaching this topic, the matching act
