Hi, I found this relatively useful because I was completely lost when understanding how to find the unit vector along x with relation to x’ and y’. I am still a little confused as to why we specifically use cos(30) and sin(30) specifically, especially sin(30) for the j direction of x rather than, for example, cos(30)
