Percentage improvement |
2010-08-26 |
|
From shahrukh:
Hi...
We had a web page that was taking 12 secs to load. Now it loads in 3 secs.
What is the percentage of improvement or how much faster is it working now.
TO me it looks like it is working 3 times faster or there is a 300% improvement in the loading time.
However my client says its ((12-3)/12*)100 = 75% improved. Which seems illogical on the face of it.
Thanks for your help

A vertical asymptote |
2010-08-19 |
|
From Kendall:
If a compound function is defined as 1/x for x<0 and 5 for x>=0
does it have a vertical asymptote at x=0? According to the definition
in my book I think it does because the left-hand limit is infinity and it
only takes one side to cause a vertical asyptote. Thanks!
