hi,(adsbygoogle = window.adsbygoogle || []).push({});

I want to know the practical use of Integration and Differentiation. I know what it is. I just wanna know how can i explain it with a practical example.

example : for Differentiation - the dy/dx can be explained that y is dependent on independent variable x. How can d2y/dx2 be explained. why is it a second differentiation required. How can it be explained practically with example.

Similarly can anybody explain me integration.

Thanks in advance
