Hi, I'm new to the forum.

I have a problem finding the coordinates of a 3D point from one coordinating system into another, which has different axes' angles.
This is very confusing (at least for me), so I'll explain what it is I actually want to accomplish with the attached image.

So, I am trying to find the location of points of local coordinating systems in the global/main coordinating system. I've used sine and cosine so far, but for some cases it just does not work, and I think I might need something else in order to calculate this, maybe vectors? I'm bad at vectors that's why I don't know whether I should use them..

I need this for 3D programming and there's lots of things I get stuck on in trigonometry and maths.... :/
