The discussion revolves around confusion regarding the application of the curl in spherical coordinates, specifically the handling of the sin(θ) factor in the aφ component. Participants note discrepancies between the textbook's expansion and their calculations, particularly concerning an extra sin(θ) when using the matrix formula. There is also mention of a potential typo related to a missing r factor in the second term of the equation. Suggestions include focusing on the determinant and applying factors last to avoid confusion. Overall, the consensus indicates uncertainty about the accuracy of the textbook and the proper application of the matrix method.

Homework Statement
Take the curl in the shperical coordinate system.
Relevant Equations
Same as below.
This is from my E&M textbook.
I'm doing a problem where I need to take the Curl in spherical coordinates but I'm getting the wrong answer.
I tried applying the matrix, but it doesn't seem like it make sense with the expansion that they show in the textbook (screenshot below).
If I apply the matrix formula I end up with an extra sinθ that don't get if I use the formula in the expansion.
It looks to me like in the component there should be a 1/sinθ factor outside the brackets?
I don't see what is happening in the compentent that is making the 1/sinθ factor next to the matrix disapear when we get to the component.
Am I missing something.

Thanks

This looks like a typo. But I have some trouble with a factor ##r## in the second term, too, missing ##r^{-1}##. I suggest to deal with the determinant and apply the factor outside last.

I get the wrong answere when I use the determinant, even though I divide through with the r^2 sin(theta) last.
I do get the right answer if I use the expanded notation as a guide. So not sure if I'm applying the matrix wrong, or if there's a typo somewhere?
 
First, I tried to show that ##f_n## converges uniformly on ##[0,2\pi]##, which is true since ##f_n \rightarrow 0## for ##n \rightarrow \infty## and ##\sigma_n=\mathrm{sup}\left| \frac{\sin\left(\frac{n^2}{n+\frac 15}x\right)}{n^{x^2-3x+3}} \right| \leq \frac{1}{|n^{x^2-3x+3}|} \leq \frac{1}{n^{\frac 34}}\rightarrow 0##. I can't use neither Leibnitz's test nor Abel's test. For Dirichlet's test I would need to show, that ##\sin\left(\frac{n^2}{n+\frac 15}x \right)## has partialy bounded sums...
