What is Differentiation

Differentiation is a mathematical technique for determining the derivative of a function involving two independent variables. 

This procedure is designed to determine the instantaneous changes that occur in one of the variables as a result of the changes that occur in the other variable. 

For example, the instantaneous change in the rate of displacement when time is taken into consideration is referred to as velocity.

If we denote it in mathematical form, the changes in variable ‘y' with regard to another variable ‘x' are stated as dy/dx, where dy is the difference between the two variables. 

If y = f(x), then f'(x) is equal to dy/dx. The derivative of f(x) is represented by the symbol f'(x). This is the general form to represent the derivative of a function. However, there exist different types of differentiation.

Directional Derivative and Second Derivative are the types of differentiation. They are slightly different concepts, and their formulas are different. You can find the directional and second derivatives using an online directional derivative calculator and second derivative calculator.

Some of the most significant rules of differentiation or the different types of differentiation are explained below.

Different Types of Differentiation Rules

Power Rule

In mathematics, the constant power derivative rule is used to calculate the derivative of an exponential term that has a variable as base and a constant as power.

The literals in the expression are x and n, one of them represents a variable and the other as constant, respectively, in a sentence. However, they combine together to produce an exponential term xn. 

The derivative of x is increased to the power n and is expressed in the following mathematical form:

d/dx (xn)

The expression above states that, x raised to the power of n-1 equals the product of n and x, which is the differentiation of the n-th power of with respect to itself. In the case of a constant power rule, the derivative can be expressed in terms of any variable or constant.

Quotient Rule

The method of calculating the derivative of a function being the quotient of two other functions. In case the ratio of two random function i.e. g(x) and h(x) is given as f(x) the the rule can be defined as

Or

We can explain this in other words that, if x’s two functions are given as h and g, then in this stance the ratio of g and h’s derivative could be denoted as

When attempting to find the derivative of a function that has been divided by another function, the quotient rule is applied during differentiation. The quotient rule is thus used to determine the final derivative is a precise mix of both of the original functions and their derivatives as long as both of the original functions have derivatives.

Product Rule

In order to define the product rule of differentiation, suppose two differential functions f(x) and g(x) are defined in terms of the variable x. Then, in calculus, the differentiation of the product of them with respect to x is expressed in the following mathematical form.

d/dx (f(x).g(x))

This implies the product’s derivative is computed by adding together the product of a first function and second function's derivative, as well as adding together the product of a second function and first function’s derivative.

Differential calculus makes use of the equality condition to find the differentiation of a product of two or more functions, which is useful in many applications. Moreover, the derivative of the product rule is sometimes referred to as the uv rule.

It may be stated in terms of u and v by substituting f(x) = u and g(x) = v and multiplying them together. The notation for the product rule is known as Leibniz's notation for the product rule.

Therefore, when you have two functions that are multiplied together, you may determine their derivatives by applying the product rule. In which the first function times its derivative plus the second function times its derivative will give you a derivative of the product of two functions.
