    Function Limit
Click For Summary
The limit of the function \(\lim_{n\rightarrow\infty} \frac{n^{(1+q)}}{e^{(\frac{1}{2})n^{(1-q)}}}\) for \(0<q<1\) is discussed, with Bincy expressing difficulty in applying L'Hôpital's rule due to repeating patterns. Bincy believes the limit approaches 0. A suggestion is made to use the substitution \(u=\frac{1}{2}n^{1-q}\) and to recall that \(\lim_{x \to \infty} \frac{x^k}{e^x} = 0\) for any real \(k\). This approach is acknowledged positively by Bincy. The discussion emphasizes the limit's convergence to 0.

Hello,

[math]\underset{n\rightarrow\infty}{Lt} \frac{n^{(1+q)}}{e^{(\frac{1}{2})n^{(1-q)}}}
[/math]

where[math]0<q<1[/math]
I tried using L' Hospitals rule but could not able to do since same pattern was repeating. I strongly believe that the limit is 0.regards,

Try putting \(u=\frac{1}{2}n^{1-q}\), and remember that \[\lim_{x \to \infty} \frac{x^k}{e^x}
=0\] for all real \(k\)

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...
