My calc final is tomorrow, and I don't have any notes for finding vertical asymptotes. This of course made me get some questions wrong on my last test, and I don't want to fuck up my final.

Anyone know?

Vertical asymptotes occur at values which are excluded from the domain of a function.

Translated into practical terms: The domain of a function f(x) is all of the values of x for which the function f(x) is defined. Which kinds of values would be excluded from the domain? Values of x which would cause the denominator of f(x) to be zero, values of x which would result in the square root of a negative number...that kind of stuff.

Hope that helps.

and I had calc last year in high school, too.

I just couldn't remember what we had to do. Setting the denominator to 0 sounds good to me, i'm sure it'll be good for the one or two questions that'll be on the final about it.

Hey jinx you know your one smart cookie. I've not taken calc yet and even i was able to understand your formula. thumbs up, seriously. I cant wait to take calc next fall along with a bunch of biology classes. Next symester is all about the english and basic math principles. I need me a trig tutor.
