it's about limit function, it's foundation for understanding diferential and integral!! take it and got the best!

1. Nice with Limit function!! By: Mr.Yong reezarschool.blogspot.com Blueboard style

2. For xa (a≠0) There are three ways to finish a limit question with xa. Subtitute Factoring ratinalization of the root

3. Example one: By subtitute:

4. Examlple two:

5. Example three: Note: Avoid the form of 0/0 !!! so, we must rationalization it!

6. Remember it!! To finish this question, you must know it: Do It!!!

7. theorms

8. For x0 It’s same with before: Yes, you musn’t make 0/0 in the limit function! Still confuse??? Go to the next slide!!

9. Example:

10. For x~ (undefined) It’s easy! You just undestandit,so you’ll be able to finish all questions with x ~!!! The first term: Don’t make : ~ - ~ or ~ / ~ The second term: The third term: divide the numerator and denominator by x^n, where n is the highest rank of the denominatorStillconfuse??? Click to next slide!!

11. Tips : It’s the most important in this our discussion!! 1 2

12. Example: At first We will try to finish it by our three terms! Remember!! We must devide with x^n, n is the highest rank of denominator……

13. Now,let us use our tips! You know m=n, L will be equal to a/p. So, we just write 3/9=1/2(it is the answer!!) same same
