Learning mathematics

Hi all,

I have to admit that I am an idiot when it comes to mathematics - I can’t seem to follow the current lectures I have for things such as geometery representations of shapes, affine transformations and so on.

So I am just wondering if there’s any good online resources for affine transformations, especially 3d. Just trying to understand rotation in 3d by reading is a major headache by itself!

Thanks in advance!

I hope this site comes helpfull.
