Hello, and thanks for the help in advance.
I have two limits I must evaluate on a practice exam, and am having a little trouble. They are both complicated enough that you cannot simply plug in the value the variable is approaching. They are listed below.
limit sin(4x) As x -> 0
limit 1 - cos(t) As t -> 0
(The periods are simply so that the fractions look right.)
I know you can pull 1/2 out in front of the limit for the first example (with x), but other than that I am at a loss as to what to do. I can do more complicated things...it's just been a while since I had to evaluate limits like this. Maybe it's a few simple things I'm forgetting?
Thanks again, I hope the way I've typed them is legible.
