# What is Derivatives and what are their methods and types?

Derivatives are the rate of change of a quantity y with respect to another quantity x. It is also called the coefficient of variation of y with respect to x. Differentiation is the process of finding the output of a job. Let’s study exactly what redemption means in calculations and how to find it with rules and examples.

## Meaning of redemption and calculation

The derivative of the function f(x) is represented by d/dx (f(x)) (or) df/dx (or) Df(x) (or) f'(x). Let’s see what it technically means. Consider the sequence of functions f(x) and assume that the two points in it are (x, f(x)) and ((x + h), f(x + h)). Then the slope of the secant passing through these points is [f(x + h) – f(x)]/(x + h – x) = [f(x + h) – f(x) / h. See the picture below and notice that when the distance between two points is close to 0 (i.e. when h approaches 0), the second point covers the origin and the secant line and – becomes a tangent line. In calculus, the slope of the tangent is called the derivative of the function. That is.

â€¢ Derivation of the function, f ‘(x) = Tangent slope = limhâ†’0 [f(x + h) – f(x) / h. This process known as measure the end of the process or) derivation using first principles.

## Type of Derivatives:

### â€¢ Derivative at a Point:

Just as we explained in an instant the average rate, we now describe the rate of change of the individual functions in terms of the average rate of change of the function f above with respect to time. The rate of change of f and a directly is called the derivative of f and a and is denoted f'(a).

You can calculate a derivative at a given point of the function without solving the long-term calculations by using derivative calculator at a point.

### â€¢ Nth Derivative:

The nth derivative refers to any of the higher order numbers of a function. The derivative of the function f(x) in mathematics is f'(x) and can be converted to its position as follows:

â€¢ The derivative of a function at a point is the slope of a tangent drawn to that point at that point.

â€¢ It represents the real exchange rate at the same time as the project.

â€¢ The speed of a particle is found by finding the derivative of the displacement function.

â€¢ An output is used to raise (raise/lower) a function.

â€¢ They are also used to find the time point where the function is increasing / decreasing and the break point where the function is turning up / down.

There are also a online tool available to calculate easily the nth derivative named higher order derivatives calculator. Therefore, whenever we see words like “slope/gradient”, “rate of change”, “velocity (given displacement)”, “maximize/minimize”, etc., it means that the concept of process is involved. The release of the service uses the first command

The derivative of a function can be obtained from the limit definition of the process which is f'(x) = limhâ†’0 [f(x + h) – f(x) / h. This process is known as variation from the first principle. Let f(x) = x2, and we will find its derivative using the above formula. Here, f(x + h) = (x + h)2 because we have f(x) = x2. Then the derivative of f(x) is,

f ‘(x) = limhâ†’0 [(x + h) 2 – x2] / h

= limhâ†’0 [x2 + 2xh + h2 – x2] / h

= limhâ†’0 [2xh + h2] / h

= limhâ†’0 [h(2x + h)] / h

= limh â†’ 0 (2x + h)

= 2x + 0

= 2x

So the subtraction of x2 is 2x. But it can be difficult to use this restrictive definition to find a solution to a complex task. Therefore, there are some methods presented (of course, from the end point above) that we can use easily in the process of differentiation.

##### Basic rules of the Derivative:

This is the main rule of the system. Let’s consider it in detail.

Power Law: According to this law, if y = xn, then dy/dx = n x n-1 .

Example: d/dx (x5) = 5×4.

Addition/Differential Rules: The addition/subtraction formula can be divided into addition/subtraction. that is, dy/dx [u Â± v]= du/dx Â± dv/dx.

Product Law: The Product Law of Product states that if a work is the product of two works, then its product is the product of the second work multiplied by the first work added to the product of the first work multiplied by and second job. dy/dx [u Ã— v] = u â€¢ dv/dx + v â€¢ du/dx. Si y = x5 ex , na a y’ = x5 . ex + ex. 5×4 = ex(x5 + 5×4)

Law of Proportions: Law of Proportions states that d/dx (u/v) = (v

â€¢ du/dx – u

â€¢ dv/dx)/ v2

Multiple Law Constants: The multiple law constant states that d/dx [c(f(x)] = c

â€¢ d/dx f(x).

that is, a constant that, multiplying by activity, results from a process that is different. For example, d/dx (5×2) = 5 d/dx (x2) = 5 (2x) = 10 x. Constant Law: The law of constant production states that the product of each product is 0. If y = k, k is a constant, and dy/dx = 0. Were y = 4, y’ = 0.
