Result:

$$ \begin{align} G_t^t &= -\frac{h'}{rh^2} - \frac{1}{r^2}\left(1 - \frac{1}{h}\right), \quad &(49) \notag\\ G_r^r &= \frac{f'}{rfh} - \frac{1}{r^2}\left(1 - \frac{1}{h}\right), \quad &(50) \notag\\ G_\theta^\theta = G_\varphi^\varphi &= \frac{1}{2\sqrt{fh}}\frac{d}{dr}\left(\frac{f'}{\sqrt{fh}}\right) + \frac{f'}{2rfh} - \frac{h'}{2rh^2}, \quad &(51) \notag\\ \end{align} $$

gpix - Mathpix but Gemini

why pay 6 dollars a month for Mathpix when you can use a Gemini wrapper? 😋

Features

• Global Keyboard Shortcut: Ctrl+Shift+S (Windows/Linux) or Cmd+Shift+S (macOS)
