Ceramic Tile Shelves

I am in geometry class and we had to do a project by the end of the quarter that had to involve with we were learning. We were learning about graphing different types of functions at the time. One of the Spanish teachers at our school needed some type of shelving system to hang ceramic tiles that her students were painting on the walls. I was trying to think about ways I could make a shelf using a sine curve. My teacher and I decided to laser cut a sine curve and mount it on the wall so the tiles could slide in and out of it. First I had to make a spreadsheet to get the coordinates of the function and then turn it into a line using a program which I then took the line and laser cut it out. When I cut it out I didn’t like the design so I tried all kinds of different ways making it look nicer. I came up with the idea of having two sine curves flipped on top of each other.
