Generally, I'd like to learn how the world works. This also extends to space. I questioned almost everything when I was a kid, so now, I want answers :smile:
Haha, that's exactly my problem. But thank you for answering. We've cleared it up with our teacher and she said it was supposed to be "around x3 axis," which makes the problem a lot easier.
Whenever I had a hard time with my Physics homework, I usually look for help from google and I keep on encountering this site. (p.s. this forum is amazing hahaha)
We were asked to form the transformation matrix that rotates the x1 axis of a rectangular coordinate system 60 degrees toward x2 and the x3 axis.
The thing is, I don't understand what it meant by rotating one axis toward the two other. Like, do I rotate x1 60 degrees toward the x2-x3 plane or...
