Differentiation is a component that you get to learn in Calculus. Newton made this process to find how a function changes its rate. You can find this at any point in time if you once differentiate it and get the final solution. There will be some initial and final values that you need to put in the function. After that, when you subtract them, you get the actual change in the rate. In higher classes, the majority of the sums and formulas come from this process. You can use the differentiation formula in various equations to derive other functions as well.

How to Differentiate in Maths?
First, you need to learn the entire table of differentiation. There you will see what you will get if you differentiate various functions. After that, you need to write down the equation that you will get. For example, the differentiation of any constant will always be zero. You need to take the numbers in common and differentiate the variables. You must differentiate it concerning the variable that is present in the question. In case there are other variables you need to treat them as constant. Make sure that you remember the sign of the answers in the formula.
You can also use the method of limits to find the final value. The general formula for this process is the limit of h→0, f(x+h)–f(x)/h. Suppose you have a function that is x square. Then according to the formula first you will find (x+h) whole square and then just x square. After that, simplify the problem to remove “h” from below. Otherwise, the entire formula will become infinite as it is divided by zero. Both continuity and this chapter go hand in hand in Mathematics. It is the first thing that you will learn before progressing to differentiation.
Linear and Nonlinear
As the name suggests, linear functions are those that have a constant slope in their graph. If you draw the graph it tends to have a gradual increment or decrement. That is why you get to find the same rate of change no matter which point you take. In certain contracts, people say that the payoffs are linear. But this may not be the case in other functions as well. Some of the functions face a change in various intervals at a point. There you will see that the graph shifts from one point to another. You need to apply other methods for differentiating these functions carefully.
Rules in Differentiation
Just like other formulas, you need to follow some rules here. When the functions are added together, its differentiation solution also gets added. You need to just find the Dy/dx for each term and keep on adding them. The same goes for the subtraction part as well. In the case of product, there is an entire rule that you need to follow. If two variables are multiplied, you need to treat them as constants turn by turn. After that just do the summation and you will get your result.
Where Can you use this in Real Life?
The main area where differentiation is used is in calculating velocity. You know that you need to calculate the rate by dividing distance by time. In case you get a function for the distance, you can differentiate it as well. This will give you the final function for the rate. Just put in the values of time and you will get the solution. Besides this, it is used in the graph for getting the tangent to slopes. It becomes much easier to get the trajectory if you apply the formulas.
