Github *finally* supports math expressions in markdown.: https://github.blog/2022-05-19-math-support-in-markdown/ Replace all math images in README.md by corresponding Latex expressions.

good first issue

Hi, in case I want to use findiff for educational purpose, showing the differences in accuracy for first, second and higher order schemes, how can I enforce the usage of...

Hi! Thank you for the fantastic library! I'm trying to simulate the wave equation using findiff, but I'm not getting the expected results even after changing the accuracy multiple times....

Is there a way to calculate the partial derivatives of a single point of a grid (without retrieving it after calculating it on the whole grid) ? I can't manage...

**How can I select, forward, backward or center scheme?**

Hi, I might be mistaken here, bit I think the theory page (https://github.com/maroba/findiff/blob/master/docs/source/theory.rst) contains a typo in the Kronecker delta. To give the desired result of $f_k^{(n)}$ it should be...
