Question

Is anyone here good at limits? It is my first semester in college too! If so, could someone give me a review on them. Have not done Calculas in a while... All tips and assistance is appreciated!

Answer 1

combination theorem

if you have something to the power of n
5^n
then divide by 5^n throughout
then sub in n=infinity (assuming it is limits tending to infinity)


if you have squareroot

sqrt(x-2)+sqrt(2)

then you multiply by
sqrt(x-2)-sqrt(2)

then sub in x=infinity (assuming the limit is tending to infinity)


lhopitals

you have a fraction
you can differentiate the top expression , differentiate the bottom expression
then make it a fraction so if you have

f(x)/g(x)
lhopitals is you want f'(x)/g'(x)

then sub in your limits

sometimes you may have to do ratio tests and stuff but im not gonna go through all that stuff

Answer 2

this
f(x)/g(x)
lhopitals is you want f'(x)/g'(x)

shoudl read

f(x)/g(x)
lhopitals is you want f '(x)/g'(x)

just so it is clear you can see it was differentiated lol

Answer 3

Do you have any specific questions?
