Pengalaman Belajar Geogebra

Salam kenal.... Pengalaman saya belajar Geogebra begitu kompleks. Asik, seru, nyebelin dan kadang bikin pusing.. Asiknya, saya jadi tu aplikasi yg memudahkan kita untuk belajar Matematika. Serunya, kita bisa membuat kreasi-kreasi di Geogebra. Nyebelindan bikin pusingnya kalo lagi ngerjain proyek tapi gak jadi-jadi. hum, pusing. Bingungnya juga kalo mengerjakan soal secara manual, mungkin karena saya kurang berlatih menghitung manual. Konsep belajar Geogebra, yang penting kita tau dasar-dasar ilmu Matematika. Intinya belajar Geogebra menantang dan menyenangkan.

GeoGebra Tools

Jump to: navigation, search

For the French version of this page, see Outils

GeoGebra 3.0 introduced "user defined tools". This means you can create your own tools for the toolbar by taking an existing construction and specifying input and output objects of your new tool.

Let's start sharing our coolest GeoGebra Tools on this page!

Mosaic tools

Mosaicos10 Tools to build mosaics with regular polygons or Penrose kites and darts.

• Only regular tiles
• Only Penrose
• Penrose/conway.ggb Penrose & Conway
• Example
• Girih pattern Create your own patterns using a set of five tiles, by Tommy Nedbal

Triangle tools

• Triangle Tools - This is a useful tool in part translated from French. It has been added to and it includes basic tools for triangles including finding the orthocentre, centre of gravity, incentre and circumcentre. It will also construct medians, inscribed and circumscribed circles

• Altitude Tool - For drawing an altitude in a triangle.

• IsogonalConjugate(point,3 points of a triangle) - Create the Isogonal Conjugate of a point P with respect to a triangle ABC. See the article in Mathworld or Wikipedia or [1]for the mapping's interesting properties.

• FeuerbachCircle(A, B, C) - Create the Feuerbach Circle (nine-point-circle) of a triangle ABC including its centre, all nine points on it and the orthocentre.

• Tangents to two circles - This tool constructs lines tangent to two circles. The theory behind it is explained here.

Calculus tools

• Complex numbers - Tools for Complex numbers, including multiplication, reciprocal, congugate and mobius transformation. (Addtion can be done by "A+B" etc. and so is not needed)

• Square Difference - Tool to display/compute the square distance between a point and a line as used by a least squares regression.

• Easy Table - Tool to create a x | f(x) table given a function, starting x value, ending x value, and step. The table will be created as a textbox. The table is limited to 99 rows (including the heading). To see a post on how the tool was created read this forum post

• function in the box - Tool to create a 'boxed' view of a function. The given function is (mathematically) clipped to a given rectangle. Just specify the function and the lower left and upper right vertices of the rectangle.

• Polynomials - Two tools for quadratic and cubic (Langrange) interpolation polynomials by 3 resp. 4 points. Be patient, rather slow performance with the cubic polynomial. ;-)

Splines

• Bezier Curves - two tools for quadratic and cubic Bezier curves
• Hermite spline - a tool to create Hermite splines
• Catmull-Rom spline - a tool to create Catmull-Rom splines
• B-Splines - a tool to create B-Splines, by Víctor Ceballos Inza

Conic sections

• Ellipse from segment and point on segment by Michael Horvath
• Hyperbola from segment and point on segment by Michael Horvath
• Parabola from vertex and focus by Michael Horvath
• Parabola(Vertex,Point) - Create a quadratic function out of vertex and another point on the parabola
• Ellipse from Two Points and Eccentricity - Create an ellipse from two points (the center and the semi-major axis) and an eccentricity value, by Michael Horvath
• Ellipse from center and two axes - Create an ellipse from a center point and two (the major and minor) axes, by Michael Horvath

Taxicab Geometry

• Taxicab Distance doesn't appear on the toolbar but is required by the other Taxicab tools below
• Taxicab Circle from Center and point on circle
• Taxicab Ellipse from foci and point on ellipse
• Taxicab Toolbox contains the tools above in a GeoGebra worksheet

Vector Tools

• Texttool that shows the correct name and the coordinates in the right matter for a vector that is defined by two points. [Where is it? The link?]

Tools for applications in Physics

Measurements

• Draw linear distance - Draw the distance between two points using a graphic style commonly used in drafting, by murkle
• Angle marker with fixed size - Creates a drafting-style angle marker with a fixed size at all zoom levels. By Michael Horvath.
• Angle marker with fixed size (outer) - Creates a drafting-style angle marker with a fixed size at all zoom levels, but the arrows are on the outside. By Michael Horvath.
• Distance marker with fixed size - Creates a drafting-style distance marker with a fixed size at all zoom levels. By Michael Horvath.
• Distance marker with fixed size (outer) - Creates a drafting-style distance marker with a fixed size at all zoom levels, but the arrows are on the outside. By Michael Horvath.
