Day 166: Real-World Conics

This week-end, after reading through my students’ exit slip answers to this question: What questions do you still have about the three conics we have studied this week, I realized from their comments, that we needed to actually see where conic sections are useful in real life, not just in my “geeky math world.”

So today we did some applications:

It was so satisfying to hear students exclaim, “Is that why satellite dishes have that funny thing sticking out beyond the dish?! and “I see how the ellipses foci actually show up in real life!”  The most precious comment was “oh, that makes so much sense now!”
