I spent about 30 minutes to understand this exercise. There is a lot of useful information in this website. It is a very informative website which is helpful in answering any Math related questions. The website is visually stimulating as well as mentally. The tools are very helpful in assisting in research and everyday Mathematical problems. I spend 2-3 minutes on all the sections from "Astroid" to "Watch of Agnesi." The material shows the curves accurately and educationally. This website is very effective because it allows us to move buttons and show us all the possible curves with their names. The quality of the website is very high and also it is very easy to use and understand. Even the first time users will find it easy and will learn from it.
