First Holiday Reflection

My first blog is gonna be about limits at infinity.

This is one of the easiest concepts that we learned
the whole year.

here are the rules if you have fraction:

1. if the degree of the top=0 bottom
you divide the coefficients.

2. if the top of the degree is greater it equals
positive or negative infinity. plug in large value
to see if it is negative or positive.

3. if the top degree is less than the bottom
degree it equals zero

if it is not a fraction use a table. plug in 100,
1000,10000 until you see a pattern.

here is an example:

lim 2x+5/3x^2+1= 0
x-->infinity


the answer to this problem is zero because
the top degree is less than that of the
bottom degree!
