Hi,
I have got two problems on page 436 of the book accessed through the link:
https://books.google.com.pk/b
ooks?id...ations&f=false
i) Why can we do direct rotation to align it with z-axis?
ii) I cant understand the angle alpha when we are rotating around x-axis into xz plane.
Some body please guide me.
Zulfi.
