##### Part 3A
Please write down the math you propose to implement to rotate the PMTs
over two angles:
$
\
t
heta
$
and
$
\
p
hi
$
, where
$
\
t
heta
$
is the polar
over two angles:
&
theta and
&
phi, where
&
theta is the polar
angle of a system of spherical coordinates with its zenith direction
along the z-axis, and
$
\
p
hi
$
is the azimuthal angle in the same
along the z-axis, and

phi is the azimuthal angle in the same
system.
##### Part 3B
It is suggested to implement two functions that do the work of the
rotation, first to obtain the parameters of the rotation from the
angles
$
