Watch this video to learn about the equation of a straight line. Since we are given 2 points that already lie on the line, using the formula as before, we need to calculate the gradient first.

To help draw a straight line graph from its equation, fill in a table of 𝑥 and 𝑦 values. Plot the pairs of values as coordinates and join to make a line. Make sure you are confident with ...

Where $\rho(\mathbf{r})$ is a charge density. The purpose of this command-line tool is to convert between these two kind of multipole moments. For example, if you have computed the Cartesian multipole ...
