## anonymous 5 years ago Improper integrals: how do i know when the limit is coming from the left or the right?

• This Question is Closed
1. anonymous

You decide how to approach the limit, and denote it as such....Lim as x->0+ or lim as x->0- Would be read as Limit as x approaches 0 from the right, etc.... You can replace the limit as x approaches 0 with x approaching any number...

2. anonymous

ex. $\lim_{L \rightarrow 7} \int\limits_{7}^{0}$

3. anonymous

proper coded notation is as follows.....using 9/x as the limit to be evaluated approached from the left.... lim_(x->9^-) 9/x = 1

4. anonymous

$\lim_{L \rightarrow 7}\int\limits_{L}^{7}1/{(x-7)^{2}}$

5. anonymous

Yes, imignott is correct

6. anonymous

How do i know when L is going to 7 from the left or the right?

7. anonymous

because the limit is on the lower bound, would mean approached from the left, or lower end of the number line.... Vice versa for upper bound and from the right...
