WAVES & BOATS
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 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.
Show your teacher your options.
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.
Save your file as Boat_TangentWave.ggb
#4 Use the tangent line to create a nice boat on the wave. Be creative.
