Most students find the Limit to be one of the most difficult tasks to grasp. The main reason for that is that they have not developed a basic understanding of the concepts. Students need to learn how to use online tools like limit calculators to have a better understanding of what they are learning. The limits can be solved by the four following methodologies:

- The substitution method
- The factoring method
- The rationalizing method
- The LCD method

Do you know that Students usually have difficulty spotting if the limit is finite or infinite. When they have no clue then it would become a thing of great concern for the students. For the finite polynomial, we are going to use the substitution and the factoring method. For the infinite function, we are going to use the rationalizing and the LCD method.

The limits calculator can be best in this regard, as it can decide which method is going to be implemented. This would be greatly helpful for the students, and they can learn which method to implement by using the limit calculator with steps. This would be helpful for the students, to find the whole procedure of knowing the limits of the polynomial.

When students are using this tool, they are going to learn automatically how to solve the limit of the polynomials. When students are cleared, when to implement which method, they can easily implement that particular methodology.

In the following article, we are trying to make the procedure of solving the limit of the polynomials easy for the student.

## The process of implementing substitution:

There are various reasons for implementing the substitution method, we need to sort out when to implement the subsitin method. The other thing, which is quite essential to know how to implement the substitution method. The lim calculator can be great in finding how to implement the limit in the polynomial.

There are different things to consider, when to implement the substitution method:

- We are putting the substitution method, when the denominator remains defined, when we are implementing the limit.

Example:

Now, when we are implementing the limit

- When the denominator of the limit becomes “0”, we are then going to implement the other methods.

**(16/0) **is an undefined function and we are going to implement the other methods here to solve the limit.

When we are using the limit solver, it would indicate at the first step that the limit is undefined.

## The process of implementing factoring:

There are certain conditions,to implement the factorization method, we are discussing them one by one:

- The first thing is to consider the polynomial that has the roots, the limit calculator with steps, which is going to indicate this at the first step.
- The other thing, which we need to consider, when we are implementing the limit by the subsitiin method.It would make the limit unsolvable for us.

Example:

In the above function, you can notice, when we are implementing the limit in the denominator. Then it is making the limit undefined, but when we are factorizing the limit, then the (x-2) would be cut down by the denominator, and the remaining polynomial would be (x-6). We simple put the limit in this function and get the answer:

The limit calculator with steps would indicate at the first step, whether the limit has the roots or not.

## The process of implementing rationalize :

There are certain reason for implementing the rationalizing method, we are going to discussing them:

- When the function has the square root, then we are going to solve the function by the rationalizing method.
- We would make the conjugate of the function,and then multiply it with the denominator and the numerator:

### Example:

Now when we implement the “13” in the denominator, we get the “0”, This would make the fraction not able to solve,We would try to make the conjugate of the limit, and then cancel it out by multiplying the denominator and numerator, we can use the limit calculator with steps to find the conjugate of the limit.

The conjugate would make the limit solvable for use, we can make the limit adjusted after we solve all the functions.

## The process of implementing LCD :

There are certain conditions to implement the LCD method,itcanbe easy toimplement the LCD method, and the limit calculator with steps can be a unique tool in this regard.

- The main reason for implementing the Least Common Denominator(LCD), is that we are dealing with the irrational number.
- The irrational number is only going to be solved by taking the LCD of the denominator.

The limit calculator with steps helps us to find that the function is irrational,and is going to find the limit by implementing the LCD method.

## Final thoughts

The limit calculator is going to find us, which method is best suited for us to implement. Students do find it quite easy to use, the main thing here is to find the distinction, Why are we implementing one of the methods? When students are able to develop the understanding, when to implement a method, they can easily solve the limit of the polynomials. When you’re using the limit calculator with steps, it would also help to develop the understanding of the virus categories of the limit of the polynomials. This can be a great help for the students, when they are solving the limit of the polynomials.
