School math, multimedia, and technology tutorials.
A good sunny Sunday morning to everyone. It’s Sunday, so let’s relax and have fun with these funny math pictures and images. Most of these images are taken from Tumblr and Facebook pages.
1. Who knew that graphs can be so sexy.
2. You’ll probably not laugh at this. That guy is Bill Cosby. Well 
Finding the center of a circle can be quite tricky in some cases, but has a practical and important applications. For instance, an ancient broken plate is unearthed and the archaeologist wants to find the length of its diameter, he can just find its center. Once the center is found, he can also find the length of the radius and hence can find the length of the diameter.
In this post, we learn how to find the center of the circle in different ways. » Read more
We enjoyed creating a two dimensional heart graph and three dimensional heart graph using the Google search engine, but we can also construct a GeoGebra heart graph. In this post, we learn how to create a heart graph using GeoGebra. The equation of this graph is a lot simpler compared to the first two (well, because it is in factored form).
How to Construct a GeoGebra Heart Graph
Open GeoGebra. You might want to display the Axes by pressing Graphics at the upper right of the Graphics view and then choosing the Axes icon.
In the Input Bar, type (x^2 + y^2 – 1)^3 – x^2y^3 = 0 and the press the Enter key on your keyboard. The equation you typed is equivalent to » Read more
