Im having trouble with a basic python assignment in one of my classes. Its supposed to ask the user for temperatures in Celsius and convert them to Fahrenheit, which it does fine. The problem is that its also supposed stop asking the user if he gives it 0, which means the end of the list of...

yes i am familiar with the summation convention, but is it assumed to be basic three dimensional euclidean space? so
\nabla_{\alpha}T^{\beta\gamma}=\sum_{i=1}^{3}\frac{\partial{T^{\beta\gamma}}}{...
I get in essence what the covariant derivative is, and what it does, but I am having trouble with the definition, of all things.\nabla_{\alpha}T^{\beta\gamma}=\frac{\partial{T^{\beta\gamma}}}{\partial{x^{\alpha}}}+\Gamma^{\beta}_{d\alpha}T^{d\gamma}+\Gamma^{\gamma}_{d\alpha}T^{\beta d}
Im good...
By folding i mean manipulating spacetime to the point where two separate points in spacetime that are very far away, become very. picture a very long thin object with a huge amount of mass. it would bend spacetime to look like a "V" if you were looking perpendicular to the third spatial...
I know that folding spacetime is completely possible, and I'm pretty sure that the answer I'm looking for is in Einstein's field equations. I just don't know enough about tensor calculus (yet) to figure this out for myself. So my question: how much energy is required to completely fold a certain...
how can i use u substitution to solve \int tan^{4}(x)dx?
I am not allowed to use a table, so i can't use the \int tan^{n}(u)du formula. I have no work since i can't even make it fit \int udu. help?
I am a little confused about the notation of tensors. could someone please explain the indexes? like what is the difference between Tmn and Tnm? and what about T^{m}_{n} and T^{n}_{m}? it would really be helpful if someone could give me an "intro to basic tensor notation" answer. i have no...
the first question i have is if i set it up the iteration right. The I've simplified to one quarter of the pyramid, so the value c is actually 1/2 the base of the whole pyramid. and h is the height of the pyramid. (the pinnacle of the pyramid is along the z axis)
0\leq z\leq -\frac{h}{c}x+h...
I'm not sure what I said made any mathematical sense, but here's basically what I meant and it appears to work.
lets say z=2x+y, so
dz=\frac{\partial z}{\partial x}dx+\frac{\partial z}{\partial y}dy
dz=2dx+dy
\int dz=\int 2dx+\int dy
z=2x+y+C
So it was just my overlooking the...
I should have put a constant of integration somewhere because I don't have any limits set up. is there a reason why indefinite integration won't work? It can't be in the constant, because that cancels if i do put limits on it. but about the z being a function of x and y, i think that is what i...
And i just figured out what i did wrong in the latex, so don't even mention it. this is what i meant, though i really doesn't change anything, it just looks better.
\int dz=\int\frac{\partial z}{\partial x}dx+\int\frac{\partial z}{\partial y}dy
