Derivative in spherical coordinates
WebSep 24, 2024 · Take 3D spherical coordinates and consider the basis vector $\partial_\theta$ that you might find in a GR book. If the definitions for vector calculus stuff were to line up with their tensor calculus counterparts then $\partial_\theta$ would have to be a unit vector.

WebWe usually express time derivatives of the unit vectors in a particular coordinate system in terms of the unit vectors themselves. Since all unit vectors in a Cartesian coordinate … WebJun 29, 2024 · 3.8: Jacobians. This substitution sends the interval onto the interval . We can see that there is stretching of the interval. The stretching is not uniform. In fact, the first part is actually contracted. This is the reason why we need to find . This is the factor that needs to be multiplied in when we perform the substitution.
WebSpherical coordinates can be a little challenging to understand at first. Spherical coordinates determine the position of a point in three-dimensional space based on the distance $\rho$ from the origin and two angles $\theta$ and $\phi$. If one is familiar with polar coordinates, then the angle $\theta$ isn't too difficult to understand as it ... WebTime-derivatives of spherical coordinate unit vectors For later calculations, it will be very handy to have expressions for the time-derivatives of the spherical coordinate unit vectors in terms of themselves. That for is done here as an example.
WebSpherical coordinates In spherical coordinates, we adopt r r itself as one of our coordinates, in combination with two angles that let us rotate around to any point in space. We keep the angle \phi ϕ in the x-y plane, and add the angle \theta θ which is taken from the positive \hat {z} z -axis: WebOct 10, 2015 · I have the following relationship, which makes use of the the material derivative: $$ (\vec {A}\cdot {\nabla})\vec {r}=\vec {A} $$ I am needing to show this result in spherical polar coordinates. Now, I don't want to be vague in what I have so far, but I really have very little. I've started with $\vec {r}$ in spherical polar coordinates being:
