MHB Finding Lagrangian description of position from Eularian velocity description

Click For Summary
The discussion focuses on converting Eulerian velocity descriptions into Lagrangian position descriptions in fluid dynamics. Participants emphasize the importance of correctly formatting LaTeX code for mathematical expressions to facilitate clear communication. The use of specific tags for inline math is highlighted as essential for proper parsing. There is a brief mention of the technical aspects of LaTeX formatting. Overall, the thread serves as a guide for effectively using LaTeX in mathematical discussions.

Hello and welcome to MHB, nemo surfs! (Wave)

In order to get $\LaTeX$ to parse, you need to enclose the code in tags. The easiest method (for inline math) is to use the $\Sigma$ button on our toolbar, which will generate $$$$ tags, and put the cursor between the tags so you can then add your code. For example:

$$\infty$$

generates:

$$\infty$$

Thread 'Problem with calculating projections of curl using rotation of contour'

Hello! I tried to calculate projections of curl using rotation of coordinate system but I encountered with following problem. Given: ##rot_xA=\frac{\partial A_z}{\partial y}-\frac{\partial A_y}{\partial z}=0## ##rot_yA=\frac{\partial A_x}{\partial z}-\frac{\partial A_z}{\partial x}=1## ##rot_zA=\frac{\partial A_y}{\partial x}-\frac{\partial A_x}{\partial y}=0## I rotated ##yz##-plane of this coordinate system by an angle ##45## degrees about ##x##-axis and used rotation matrix to...
