Lindsey's Reflection

This week i am going to go
back and do this blog on
limits at infinity just to brush
up on this concept.

---if it is a fraction there are three
rules that you have to use when
trying to solve it.

1. if the degree of the top and bottom are
the same you divide the coefficients.

2. if the top degree is greater than the
bottom degreee it is going to equal
either infinity or negative infinity.
you have to plug in large values
in your table to see which one of these
it is going to be.

3. if the top degree is less than the bottom
degree it is going to equal zero.

---if it is not a fraction use a table.
you plug in 100,1000,10000 and so
on until you see a pattern between the
numbers.

here are some examples using these
rules:

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

the answer is gonna be zero because the
top degree is less than the bottom degree.

lim 2x^2+3/4x^2+5=1/2
x-->infinity


the answer is gonna be 1/2 because the degrees
are the same so you would divide the coefficients.

see everyone tomorrow.
