$2r(s^2+1)dr+(r^4+1)ds=0$
This is the second question in the textbook and I am able to do every question after it, so perhaps there is something simple that I am not seeing? The answer has no trig functions in it.

# Autocorrelation Function Question
1. May 3, 2010

Hi, we're learning about the autocorrelation function at uni, and I know it's meant to show similarities between a function and a delayed version of that function. But how does the autocorrelation show these similarities?
For example, if$$x(t)=Asin... | |

# Dimensional analysis
## Approach
Dimensional analysis is very important to interpolate the experimental laboratory results (prototype models) to full scale system. Two criteria must be fulfilled to perform such an objective. First, dimensional similarity, in which all dimensions of the prototype to full scale syste... | |

1. ## continuity problem (domain)
Hello, I don't understand why the answer for the domain is wrong.
Can anyone tell me the correct answer?
Thank you.
2. ## Re: continuity problem (domain)
$Q(x)$ isn't defined for $x = \sqrt[3]{3}$
therefore the domain of $Q(x)$ is $(-\infty, \sqrt[3]{3}) \cup (\sqrt[3]{3},\infty)... | |
