Photo Description: The linking ropes that border the MacDonald bridge resemble a cosine function with a vertical translation of 1. Although this photo was taken ‘back in Mr. Lee’s day’ the bridgestill looks the same today.
A Note from Mr. Leeabout suspension bridges: A free hanging rope or chain follows a curve that is called a catenary.The equation for a catenaryis pretty cool and we'll look at it whenwe get to chapter 3.7 in the textbook("Modeling with Exponential and Logarithmic Functions").

Mr. Lee's Example Photo
I saw this building while I was at the cross country provincial championship meet. I thought the roof would make a nice piecewise function.I'm trying to be a bit more precise here with my functions soI loaded the image into the background of a Geometer's Sketchpad file. Then I played with the functions until I got them to match up with the roofline fairly acurately.
