How To Find The Values Of Trigonometric Functions Very quickly

For finding the value of sine and Cosine, see the number of fingures on right and left respectively of the selected angle and then put total number of fingures in under radical sign. After simplification we get required values of sine and cosines.

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.
