Reflection: Exit Tickets The Circle (Day 2 of 2) - Section 3: Practice and Closure

 

Here are three exit slips from today's lesson. The first student is concerned about an idea that was taught in geometry but he has forgotten.  I will talk to this student and review how to find the distance.  I will draw the a diagram and remind the student about making an right triangle. After doing that I will define the distance formula for the student.

The second question is about the last 3 problems on the homework.  This student wants to know how to determine when two circles will intersect.  After the student turned in the exit slip I was able to discuss this with him.  He had also talked to another student about the problem. These students decided they needed to show that the distance between the 2 centers is less than the sum of the radii. 

The final student realizes that somewhere in our course the trigonometric functions will connect to conics.  I will be developing the equations of conics in the polar coordinate system in the next unit so the trigonometric functions will reappear.

The Circle (Day 2 of 2)

Unit 5: Conics
Lesson 2 of 13

Objective: SWBAT convert the equation of a circle from standard form to general form.

Big Idea: Applying the equation of a circle to solve problems requires students to use different forms of the equation.
