Applied Mathematics - ll : Limits | Chapter 01 | Lecture 04 Notes For Polytechnic.

Hey Everyone, I will show You Algebra Of Limits , Addition, Difference, Product & Quotient Of the limits Of the Functions & also Evaluation Of algebraic Limits.


Limits Lecture 04 ( Topic )

1)  Algebra Of Limits .

- Addition 
- Subtraction 
- Product 
- Quotient 

2 ) Evaluation Of Algebraic Limits. 

We Use different ways to evaluate the algebraic Limits they are,

- Direct Substitution Method 
- Factorisation Method
- Rationalisation Method
- Some Standard Method
- Algebraic Limits at Infinity

3 ) Question Based on Direct Substitution & Factorisation method.

Algebra Of Limits 

1 ) Limits Of Sum if two function is sum of the limits of the functions.

        Lim { f(x) + g(x) } = lim f(x) + lim g(x) 
        X→a                           X→a.         X→a

2 ) Limit of difference of two function is difference of the limits of the functions.

         Lim { f(x) - g(x) } = lim f(x) -  lim g(x) 
         X→a                            X→a        X→a

3 ) Limits Of product of two function is the product if the limits of the functions.

          Lim { f(x).g(x) } = lim f(x).lim g(x) 
          X→a                       X→a        X→a

4 ) Limit Of Quotient Of two functions is Quotient of the limits of the functions.

           Lim { f(x)/g(x) } = lim f(x)/lim g(x) 
           X→a                       X→a       X→a

Where, Denominator is non zero .


Evaluate of Algebraic Limits .

We Use different ways to evaluate the algebraic Limits they are,

- Direct Substitution Method 
- Factorisation Method
- Rationalisation Method
- Some Standard Method
- Algebraic Limits at Infinity


Question Based On Direct Substitution Method 
- We Substitute the value of limit directly in place if x .

Consider,
                       lim f(x) = f(a) Exist 
                         X→a
