Two thin convex lenses of focal lengthf(...

Two thin convex lenses of focal length`f_(1)`and`f_(2)`are separated by a horizontal distance`'d'`where`(dltf_(1) "and" dltf_(2))` and their optical centers are displaced vertically by`x_(0)` .Taking the origin at the centre of lens `L_(1)`consider the following cases when a parallel beam of paraxial rays are coming form left.
