comment How to find the partial derivative of this function?
Yes that is the reason. Thank you

comment How to find the partial derivative of this function?
@pbs, the notation is saying the change in $\nu$ with $T$ while keeping $P$ constant. That is the notation my professor has given us and also how it is shown in the Thermodynamics book. I was just trying to be consistent

comment How to determine gradient of vector in cylindrical coordinates?
@DoctorDan that resource is very helpful. I took multivariable calculus about 4 years ago and we are having a review in my graduate level fluid mechanics course and I am trying to remember all this stuff. Am I right in saying that the gradient of $\hat{V}$ in my original post is a vector and the divergence would be a scalar?

comment How to determine gradient of vector in cylindrical coordinates?
I am working on a problem where I am trying to find the divergence of the vector in cylindrical coordinates but I need to find its gradient in order to do that. I have found the general form of the gradient online but I would like to understand how that was produced instead of copying it

comment How to determine gradient of vector in cylindrical coordinates?
Yes that's what I meant. Sorry. The function I would be dealing with is still the one above

comment What function satisfies these conditions?
I was dealing with a PDE for the non-homogeneous wave (string) equation which I believe was $u_{t}-u_{xx}=e^{t}$ and the first step in dealing with this type of problem was to find a function, $v(x,t)$ that satisfied the boundary conditions and the initial condition which were given to me. God I feel like an idiot not being able to to determine the function so I did all the other steps without it but not having it is probably gonna hurt me. I wish you guys were there helpin me today!

comment What function satisfies these conditions?
I just took a partial differential equations exam and I had to find a function $v(x,t)$ to satisfy these two boundary conditions: $$u(0,t)=0$$ $$u(a,t)=0$$ and this initial condition: $u(x,0)=0$. I was stuck on this for most of the test and could not figure out $v(x,t)$ so I did the whole problem without it. What is it, it was driving me crazy

I was able to do the rest of the problem. That was the first step of many. Thanks a lot!

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
