Android Graphs Experiments

Graphing experiments on Android.

Mathematics has always been fascinating, and the work of visual and recreational mathematicians is incredibly inspiring. Creators like Grant Sanderson (3Blue1Brown) and Khan Academy have played a huge role in shaping an intuitive understanding of mathematical concepts, making abstract ideas visually engaging and accessible.

Android Graph Experiments is my first pet project, which I started during my internship at my first job while learning calculus, pre-calculus, and Android development. It reflects a deep interest in mathematical visualizations and function plotting.

Features:

• Function plotting with smooth rendering.
• Support for various mathematical equations.
• A dynamic and interactive graphing experience.

Known issues [WIP]:

• Remove AsyncTask in SurfaceRenderer
• Migrate to Kotlin
• Bug fixes, refactoring drawing policies and attributes
• Add Jetpack Compose support

Example: Butterfly Curve

One of the visually striking curves that can be plotted is the Butterfly Curve, defined by the parametric equations:

$$ x = \sin(t) \left(e^{\cos(t)} - 2\cos(4t) - \sin^5\left(\frac{t}{12}\right)\right) $$

$$ y = \cos(t) \left(e^{\cos(t)} - 2\cos(4t) - \sin^5\left(\frac{t}{12}\right)\right) $$
