 Mar11 comment What function satisfies these conditions? actually there was a third condition that i just saw and it was $u(x,0)=x$ so your function satisfies that as well. Thank you Mar11 accepted What function satisfies these conditions? Mar11 comment What function satisfies these conditions? Is there anyway to determine this other than trial and error?

Thank you for the clarifying that I need to differentiate between t and s domains. Actually my homework involved finding the transfer function to this differential equation. I didn't think many on the math page knew about transfer functions but they could at least let me know if I was doing the Laplace correctly. Nov12 comment Did I use Laplace correctly? Yes I am sorry. This is the equation for an object's response to a step change in temperature. So $T_{a}$ is a constant as the ambient temperature and $\tau$ is the time constant. They are both just constants Nov12 asked Did I use Laplace correctly? Sep21 awarded Supporter Sep21 accepted Which is a better measure of uncertainty: standard deviation or resolution uncertainty?

Jul19 comment How to solve a polynomial inequality? @Ross Millikan, thank you for the help but unfortunately graphing calculators are not allowed to be used in her class. If they were then she would have been able to find the answer and I would have not had to ask this question. I am just trying to teach her this stuff but the method that I said I was using wasn't taught to her yet. Jul19 comment How to solve a polynomial inequality? @The Chaz, Nobody is referring to themself in the third person. Like I said, this isn't for me. I'm an engineering student at Georgia Tech, and I haven't done things like this since 8th grade. All I asked was if there is another method of going about it since clearly her teacher put it on the test before teaching the method that I know of. As you can see, I know the most common method but it wasn't taught to her yet Jul19 comment How to solve a polynomial inequality? well the professor put it on a test ebfore they learned that material, so there must be another way
