5. Today's Objective Unit 12, Objective 1: I will be able to graph polar points and polar equations. (Day 2) Section 9-1, pgs. 553-560

6. More Polar Graphing

9. CONSIDER THE FOLLOWING: How could you find the distance between two points on the polar coordinate system?

14. Example 3: Before large road construction projects, or even the construction of a new home, a surveyor maps out characteristics of the land. A surveyor uses a device called a theodolite to measure angles. The precise locations of various land features are determined using distances and the angles measured with the theodolite. While mapping out a level site, a surveyor identifies a landmark 450 feet away and 30 degrees to the left and another landmark 600 feet away and 50 degrees to the right. What is the distance between the two landmarks?
