As some of you know, I've been renovating a viking camp and turning it into a math creativity center. Last week we were building a new railing for the deck. One of my guys asked what kind of math we want to put into it... and he wanted to start the next day. Came up with a fast idea - place horizontal support nearer the top and bottom to leave the middle open and cut a sine curve through the railings.
I drew the curve using geogebra and projected it on a piece of wood to use as a template. With some careful adjusting we got it just the size we wanted (184 cm wide by 36 cm high). My guy Thomas then cut out the curve from the sheet and traced it onto the railing and made quick work of the pattern.
I'm very happy with the result. It was quick and easy and makes nice shadows. Plus, the company name is Matematikkbølgen which means "The math wave", so a sine curve is fitting. Next step is to trim down the bushes so it's more visible from the parking lot.
