matter see how a bunch of points two-dimensional and if you visualize this an XY coordinate the Cartesian coordinate the they're clearly two separate clusters but it's harder to visualize how to linearly separate them but the moment you visualize them in the polar coordinates you can clearly say that there are two different radii and a lot of different angles and so you can have draw linearly separable hyperplane between them so it's clear that representation matters so once you move from the Cartesian representation to
