Informal way to define Derivative
Informal way to define derivative
This is an informal way to define derivative of an identity function. We know that an identity function is defined as y = f(x)=x When we will take its first derivative then their result will be y'=f'(x)=1. if will take its second derivative then it will be equal to zero.
Similarly, the following figure represents first and second derivatives of an identity function. This figure helps us to understand the concept of derivatives and it is an informal concept of derivative but not formal.

What is Pi day?
Pi day and Pi approximation day are two holidays that celebrate the mathematical constant (Pi).
Pi day is celebrated on March 14 (14/3) due to pi being roughly equal to 3.14.
Pi approximation day is celebrated on July 22 (22/7) due to pi being roughly equal to 22/7.
The first pi day celebration was held at the San Franciso Exploratorium in 1988. The staff and public marched around the circular spaces and consumed fruit pies.
