Drawing with GeoGebra

Curve Fitting with Geogebra
Step 1. Insert an Image into Geogebra.
Step 2. Tell the computer where your curve is.
Step 3. Choose a type of regression and use it!
Step 4. Examine your results in the geometry and algebra windows.

“drawing” project, where students converted an actual picture into a mathematical picture by fitting functions around the outlines and then using integrals to shade in the area between.

Basic steps (more detailed procedure below):

    Upload a picture into GeoGebra and scale the axes to the right scale.
    Place points around all the outlines making sure to hit critical points
    Fit functions to the outlines.
    Use integrals to shade in the areas between the outlines. The basic syntax looks like this…
    which means the integral between the [top function f, and the bottom function g, from x=1, to x=4].
