Derivatives

Derivative is an important part of calculus.Derivative is defined as the small rate of change of a function with respect to the variables of the function.

There are many application of derivatives.See the following link for application of derivatives help.

The process of finding the derivatives is known as differentiation.Many formula are used in finding the derivatives.Following are the formula used in differentiation.
The sum rule - u(x) + v(x) = du/dx +dv/dx
The product rule - u(x)v(x) = u(x) dv/dx + v(x) du/dx
The quotient rule - u(x)/v(x) = (v(x)du/dx - u(x)dv/dx)/(v(x))^2
The chain rule - y(u(x)) = dy/du du/dx

 Next time we will learn about problems on application of derivatives.
