Limitsssss

Infinite Limits can go on forever the bigger the number is.

-If you have a fraction with 2 polynomials divided use the these rules: (Refers to exponents)

1. Degree of top = degree of bottom leading coefficient/leading coefficient

2. Degree of top > degree of bottom + or - infinity (plug into equation to see if + or -)

3. Degree of top < degree of bottom 0



If it isnt following the rules then you...

1. Type the equation into y= in calculator

2. Hit 2nd table

3. Type in numbers 10, 100, 1000, 10000. Do more numbers if needed to see what number the equation is approaching.



*If it is geometric (has #^n)

1. If r <1 = 0

2. If r >1= + or - infinity



Examples: Find the limit of

A: (b+1)/b

The exponents equal eachother so the it is 1
The limit is 1

B:
Lim n -> k^2+3/2k^2-3
Top and bottom are equal so the limit is 1/2
