# Did you know?

This is a new project launched by MathCity.org. The soul purpose of this project is to aware the students about those concepts of mathematics which are elementary but students don't bother to dig-deeper for those concept. Also our aim is to stimulate the mind of students to think about the core concepts of mathematics.

Here is the list.

- Consider two functions $f(x)=x+3$ and $\displaystyle g(x)=\frac{x^2-9}{x-3}$. Is $f=g$? (See the details)
- What is the value of $\pi$? (See the details)
- Its about the square root (See the details)
