If you want to know what's twosided limits is, A two sided limit is just the regular limit you see denoted by the lim as x approaches some value of a function. It means that if you approached that value from both sides of the graph you would arrive at the same place. A one sided limit means if you approached the graph from one particular side (from the left or from the right) you would get different values. If the limit from the left does not equal the limit from the right side of the graph, the overall limit does not exist. For example, a function such as y = x, for x > 0 cannot have a negative xvalue. So the limit of this function from the left would not exist because the graph doesn't exist there, but the limit from the right would be 0.

factor the top and the bottom to get \[x(x+3) \over (x+3)(x3)\] cancelling gives you: \[x \over x3\] now you can simply plug in 3.

if you plug in lim 3^(+) you will get the same answer which means the limit exists

thanks.....so what if there was an indeterminate like 40/0 or something, how will I go about solving that?

4/0^(+)= + infinity 4/0^() =  infinity If you get 0/0 you did something wrong unless the prof teaches you L'hospitols rule

remember you are not using 0 but something infinitly close to zero

thus 4 or any real number would go into it infinity number of times

does that answer your question?

if you had 1/0^() = + infinity make sure to note that because a / = +

are you still confused with something?

if you take the limit from the 0+ of 1/x you get +infinity and if you take the limit from 0 you get infinity I think I made a mistake with the graph, but yeah the out put as you approach from the right is always increasing and the output from the left is always decreasing

for these type of questions you multiply by the conjugate so multiply the top and bottom by ((x)^(1/2) + 2)

no problem you should be pretty set for limits now if you understand limits going to infinity

i understand limits going to infinity but i need a resource for some twosided limit problems. it's kind of confusing/

did my 1/x example not help? 1/0 = something like 1/0.0000001 where as 1/0+ = something like 1/+0.000001 Only these numbers are infinitely small so we end up with lim 1/x = infinity x> 0+ lim 1/x = infinity x > 0 Look at the graph of 1/x dw:1329981425836:dw Notice how the output is forever decreasing from the left as you approach zero whereas the output is forever increasing from the right as you approach zero

thus the limit does not exist

if you took the limit of 1/x you would get the opposite if you took limits at both side so 0+ = infinity 0 = +infinity

as the graph looks like dw:1329981639188:dw

if you took the limit of 0+ and 0 of x you would end up with 0 and 0 which means that the limit exists

ok good I was getting tired of explaing it although I should have did it right the first time
