• # WAVES & BOATS

Introduction

In the Netherlands a lot of people live below sea-level. So you can understand during the last centuries the Dutch people put a lot of energy in working with and against the water. So are you today 😊

Watch Boat_Introduction.mp4 and you’ll see what your goal will be.

Now you know what to create. Do you need help or can you do it yourself?

#1

#1 Discuss what kind of functions you can user for the waves. How can you make them kind of irregular? Try it in geogebra. Save all your trials as Boat_wave1.ggb and Boat_wave2.ggb etc etc.

You know have a nice wave. You’re going to create a floating point on it.

#2  Create a floating point on your wave. Save the file as Boat_WaveWithPoint.ggb

(Hint: you should use a slidebar for the x-coordinate of your point)

The boat should float as steep as the wave. In order to arrange that you should derive the wave-function and create the tangent (raaklijn, tangente) in your floating point.

#3  Create the tangent in your floating point.
