comment If an analytic function has an algebraic order $h$ at infinity then $\lim_{z\to\infty}z^{-h}f(z)$ is not zero nor is it infinity
My question is why $\lim_{z\to\infty}z^{-h}f(z)\not =0$ and $\lim_{z\to\infty}z^{-h}f(z)\not =\infty$. Here $h$ is the algebraic order of $f$ at infinity.

Ah, but $(-5,0)$ is outside the rectangle.

comment Newton's method for the brachistochrone
Thank you, sir. What about positivity of the derivative, does that follow from considering the given potential and endpoints? @Thisismuchhealthier.

I'm sorry, could you elaborate on that? @Shine

This looks like the method of variation of coeficients, exept you consider $C_1(t)x_1(t)$ instead of $C_1(t)x_1(t)+C_2(t)x_2(t)$.
