MHB What is the correct power series for $g(t)$?

Click For Summary
The discussion centers on determining the correct power series for the function \( g(t) \). A proposed series, \( g(t) = \sum_{n=0}^{\infty}\frac{g(t)}{n!} \), is identified as incorrect, as it only represents the zero function. The correct formulation is clarified as the Taylor power series, expressed as \( g(t) = \sum_{n=0}^{\infty} \frac{(t-t_0)^n g^{(n)}(t_0)}{n!} \). This series uses derivatives of \( g \) evaluated at a specific point \( t_0 \). The conversation concludes with an acknowledgment of the initial misunderstanding regarding the series representation.

What would be the power series of $g(t)$?

$$
g(t) = \sum_{n=0}^{\infty}\frac{g(t)}{n!}
$$

This?

?? What EXACTLY are you trying to do? I'm guessing the recursive definition you have suggested is not a good way to go.

There is a mistake in your post, as posted there is no such function other than the zero function.

The power series of a function around a point \( t_0 \) is $$ g(t) = \sum_{n=0}^{\infty} \frac{(t-t_0)^n g^{(n)}(t_0)}{n!} .$$ Note that the \( g^{(n)}(t_0) \) denotes the derivative evaluated at \( t_0 \), where \( g^{(0)}(t_0) = g(t_0) \).

Does this help you?

Edit: Sorry, to be specific this is the Taylor power series.
 
There was a mistake in what I was reading, i.e. is read it wrong. I see what my issue was so the question I asked was wrong.
 
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...
