![]() ![]() The integration of GeoGebra into ACODESA method also fostered some process aspects of mathematical reasoning (generalizing, conjecturing, and justifying) on parametric equations. Open Middle: Parabola Equation (1) Writing the Equation of a Parabola Given Vertex and Focus. It became apparent that the participants constructed parametric equations from existing knowledge of trigonometric identities, definition of function, and general form of the equation of a circle by making connections between algebraic and geometric representations. Results of the study indicate the use of GeoGebra in ACODESA method triggered a sense of understanding of parametric equations. ![]() The collected data were analysed based on Toulmin's model. Pay attention to the initial point, terminal point and direction of the parametric curve. You can set the minimum and maximum values for. You may calculate the length of a vector v using length sqrt (v v) or length Length (v) You can get the coordinates of the starting and terminal point of a vector v. Graph parametric equations by entering them in terms of above. The default parametric curve is given by. Use the slider t or the run button to move the point A along the path in 2D. ![]() Example: You can create the midpoint M of two points A and B by entering M (A + B) / 2 into the Input Bar. SimReal - GeoGebra - Parameterization 2D. Sum: Shows/Hides the graph of their sum (the equation is shown at the upper right) Point Only: Shows/Hides just the point that is being traced out on the graph of. Data were collected through students' written productions, screen recorder software, and transcriptions of the students' argumentations for selected groups. In GeoGebra, you can also do calculations with points and vectors. Using the graph above we can see what happens when we add two sets of parametric equations together. The participants of the study consist of 24 university students enrolled in a mathematics education programme at a state university in Turkey. This study examines how collective argumentation in the integration of the ACODESA method (collaborative learning, scientific debate and self-reflection) and GeoGebra can help students understand parametric equations. ![]()
