**Background**

In calculus the two major concepts are differentiation and integration. To study small changes in quantity with respect to change in another quantity is defined as derivatives, whereas the integration is summation of small and discrete data which can not be added representing a single value.

The real life example of differentiation is velocity which is the rate of change of speed with time and in integration the area under the curve is found by integration for large scale industries.** Integral calculator** is an online tool used to find the integral of any function. You can easily find your answer using this tool.

**Differentiation**

A derivative can be defined as the instantaneous rate of change of function. The change is based on one variable. It can be used to calculate the slope of a tangent to a curve or function at a given location. Consider a point P where the slope of the tangent line is to be found.

You can find the slope of a line by drawing a tangent to point P. This line is known as the secant line. The derivative is actually the rate of change of function with respect to x at a certain point a . the derivative of any function f(x) is represented by f’(x).

If we know the derivative of the function, f’, which is differentiable in its domain, we can determine the function f. f is the antiderivative or primitive of the function f’ in integral calculus.

## Differentiation as Rate of change

The slope of the curve of the mathematical function f(x) displayed as a function of x in geometry is the derivative of a function. However, the consequences for nature modeling go much beyond this simple geometric application. After all, you could draw finite triangles to determine slope, so why is the derivative so important? It is significant because many physical phenomena, such as velocity, acceleration, and force, are defined as instantaneous rates of change of some other quantity. The derivative can provide you a precise instantaneous number for that rate of change, allowing you to simulate the desired quantity correctly.Integrals are the inverse of derivatives and can be found using an integral calculator, a free internet tool.

**Integration**

Integration and differentiation are reversible processes. The area under the curve of the mathematical function f(x) shown as a function of x can be used to calculate the integral of a function. You may imagine drawing a huge number of blocks to approximate the area under a complex curve, with more blocks yielding a better solution.

**Integration as summation**

The integral provides a mathematical method for drawing an unlimited number of blocks and obtaining an exact analytical formula for the area. That’s important in geometry, and even more so for the physical sciences, since many physical entities may be defined mathematically, such as the area under a curve. There is a separate tool for finding definite integrals which is the definite integral calculator. A definite integral is one which has limits and the answer is in numerical form.

Finding the center of mass of a continuous body, for example, requires weighting each element of mass by its distance from an axis of rotation, a process that requires the integral if you want a precise number. A large number of physical problems have solutions that include such infinite sums, making the integral a necessary tool for the physical scientist.

**Conclusion**

Differentiation represents a function’s rate of change. Integration is the accumulation or sum of a function over a certain range.

They are completely opposed to one another.. Differentials are important in physics, engineering and economics or any field that deals with changing quantities continuously. Differentiation helps in understanding the instantaneous behavior of a function which enables us to have real-world insight into system behavior. integral calculator is an online mathematical tool which is used to find the integral of a function.
