For example the angle of view is 100 degrees in lens x with full frame
camera and the crop factor is 1.5 in smaller frame camera . So what would be
the final angle of view with that smaller frame camera with that lens x.

For telephoto focal lengths, merely divide the original field angle by
the crop factor. This will work reasonably well except for wide angle,
where you do need to use the trig functions (tangent). So for the wide
angle you must actually take focal length and half of format size (36
mm/2 =18mm) divided by crop factor. Then take ratio of that format
size and lens fl, take arctangent of ratio.
