Need some help understanding what exactly I'm supposed to be doing.
Not sure if this is the right forum:cool:

Here is what I'm being asked:

Rotation by 90 degrees about the axis parallel to n = 2i - 2j + k passing through the point p2 = (2, 2, 2)

For the matrix T2:

-write the transformation matrix as a general expression involving translation matrices and a rotation with the origin fixed;

-state the general form for the rotation matrix from (i) and the values of the parameters (nx, ny, nz and cos(theta), sin(theta)) to be used

There is more, but I just need a hand starting this question.

Any help or advice would be greatly appreciated.

Help a math bro out bro... plz
Whoever told you that this is an on-demand service with paid tutors waiting on-hand to provide instant replies was, I'm afraid, quite mistaken. These forums are exactly what they appear to be: an environment where students can receive help from volunteers who surf by when they are able. Sorry.

Please reply with your thoughts and efforts so far (or else a specification that you need lesson instruction first). Thank you! ;)
