====== 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 $f=g$? ([[dyk:1|See the details]]) - What is the value of $\pi$? ([[dyk:2|See the details]]) - Its about the square root ([[dyk:3|See the details]]) - Is it difficult to answer? 1−−−0.999...
