When tidying up my storage on the last weekend, I accidentally found my old undergrad archives. Well, it's quite surprising so many things I made. Especially, I just realised that I wrote code for helping me to understand polar coordinate (Hell yes, I did some coding stuff in Calculus course). Motivated by a willingness to share with others, I post my polar coordinate plotter.

It's a very simple program actually and it's coded in Java language. Well, armed with mathematical equation parser feature, it becomes a handy tool when you need to know how the shape is like for a particular polar equation in a timely manner. A good calculator can do that, but, it's better to type the equation on a computer keyboard rather than on a numerical calculator keyboard rite?
