I'm tasked with finding the matrix of a transformation $F$ such that it is a rotation with an angle $\theta$ with respect to the point (1,0,1).
I do not fully understand this as a rotation has only one angle. Does this mean I'm rotating on the axis defined by the vector (1,0,1)? When a problem like this comes up, usually what is it asking to do?
I've found some questions on here asking for help in similar problems (given a point, find the rotation with a given angle) but all I've found is in $\mathbb{R}^2$ and for that case I understand that you're meant to use a translation then rotate and then translate back. Is it something similar?
P.S If it helps, this is in a projective geometry course.
