#### Consider the following limit. lim x→3 (x2 + 9) Find the limit L. Find δ > 0 such that |f(x) − L| < 0.01 whenever 0 < |x − c| < δ. (Round your answer to five decimal places.)

I understand how to find the limit, but I do not understand how to find the second portion. Any help would be great! Cheers :)

#### Consider the following limit. lim x→2 (3x + 2) Find the limit L.

Well I know that the limit L is equal to eight. I know I get 8 by plugging in the 2 into 3x+2, but then it asks me the following:
(a) Find δ > 0 such that |f(x) − L| < 0.01 whenever 0...

#### Determine whether the sequence converges or diverges. If it converges find the limit.

an=e(-1/sqrt(n))
Apparently in converges and the limit is 1 but I'm not really sure how to do this type of problem with a limit of ex

#### Is there a number to "a" such that the limit exists? If so, find the value of "a" and find the limit. If not, explain why.

Find the limit as "x" approaches 3
F(x)= (2x2-3ax+x-a-1)/ x2-2x-3
**I already know that if you substitute in 3 for x, the denominator will be 0 and therefore it cannot exist. I'm wondering if...

#### Can anyone help with a limit question containing cosine?

I need help finding the limit of x as it approaches 0 for (cos(x+(pi/3))-(1/2))/x.
I feel that the first step is reducing the equation to: ((cosx*cos(pi/3) - sinx*sin(pi/3))/x) -1/2x

#### can the product of two limits, one defined, the other DNE, be defined, or will it also be DNE?

Let's say you have: if lim x->a f(x) exists, lim x->a g(x) does not exist, could f(x)g(x) exist?
By that same vein, if lim x->a f(x) exists, lim x->a g(x) does not exist, could...
