A deep learning of Integration and Derivative

Glimpse From The Past rnThe universe, where we are dwelling, is in continuous phenomena of variations. Finding the reasons behind these natural changes have always been the most intriguing desire of humans with thinking minds. They tend to find the relationship between every new change and its effects. The arithmetic operations like ratios, multiplications, and additions are examples of finding these variations in the numbers system. The problem arose when it was needed to determine a change between the small intervals of time. rnAlthough this question is still held under observation in the naturalist circle, Sir Isaac Newton and Gottfried Leibniz did groundbreaking advancement in this regard. Their work led to the formal syntactical construction of the subject, which we call Calculus. The derivation and Integration are the most seminal pillars which extend the Calculus. rnDerivation rnDerivation occupies a central space in the field of applied mathematics. It discusses the rate of change at a certain point. The process of finding this rate of change in any function is called differentiation or derivation.rnWe can calculate the rate of change by calculating the ratio of change in a dependent variable with respect to the change in an independent variable of a function. In most cases, change in the independent variable and change in a dependent variable is denoted by Δx and Δy respectively.rnThis process might sound similar to that of estimating the average slope between two points. If it is the case then you are heading in the right direction. rnThe derivation is all about slope because the slope is itself an instant change in the curve. There are a certain number of rules in derivation that lead to finding the rate of change in any function. Let’s dive into them,rnThe Constant Rule: If there exists a constant integer in the way of derivation, it simply says that there is no curve and a point lies on the horizontal axis. Thus, it will produce zero. f(x)= c will become f’(x)=0 rnThe Power Rule: In the case of variables with power, their exponent will be replaced to the beginning of the variable, and the power of the variable will be reduced to one degree. rnf(x)= x4 will become f’(x)= 4x3 rnThe Constant Multiple Rule: If the function begins from a coefficient then this rule states that it would remain there and you should differentiate the rest. f(x)= 4x2 will become f’(x)= 4(2x)= 8xrnThe Sum Rule: If the function contains an addition between them, you should differentiate them separately. f(x)= x2 + 2x will become f’(x)= 2x + 2rnThe Difference Rule: like the sum rule, in case of difference you should follow the same pattern. f(x)= x2 - 2x will become f’(x)= 2x - 2rnIntegration rnIntegration as its literal meaning conveys, it is the process of summation and adding up the components. Formally, it is the inverse of differentiation and it helps in determining the volume, and area under the curve. As derivation helps us in finding the rate of change between two points on a curve, parallelly but in a different manner, integration helps us to measure the extent of change occurring between those points. Graphically, the derivation deals with the projection of certain points on its respective axis while the integration is the shaded area below these points of a curve. rnIn a bid to achieve accuracy, in integration, the shaded region becomes fragmentized, and adding these each rectangular strip gives the area of that region. rnDue to its nature of summation, integration denotes by ∫. ∫f(x) dxrnIn case of given points a, and b, a∫ f(x) dxrn brnLike differentiation, integration also follows certain rules which are listed below.rnMultiplication by Constant: The constant will remain untouched and integrate the rest. ∫cf(x) dx will become c∫f(x)rnPower Rule: The power of function will be treated specially, i.e., ∫xn dx will become xn+1 +crn n+1rnSum Rule: The sum rule pattern will be the same as it was in the derivation. ∫(h+g)dx= ∫h dx + ∫g dx + crnDifference Rule: The difference rule pattern will also be the same as it was in the derivation. ∫(h-g)dx= ∫h dx - ∫g dx + crnFor learning and solving equations of integral and derivatives on runtime without spending a lot of time, one can use online free tools like this online integral calculator and leibniz notation calculator.
