(d)	none of above

An anallatic lens is provided to make the additive constant equal to

(a)	100
(b)	0
(c)	100 and 0
(d)	none of above

The multiplying constant is denoted by

(a)	f + i
(b)	f - i
(c)	$\frac{i}{f}$
(d)	$\frac{f}{i}$

The additive constant is denoted by

(a)	$f + d$
(b)	$f - i$
(c)	$f \times d$
(d)	$f \div i$

When the line of sight is inclined and the staff is held vertically, the horizontal distance is given by

(a)	$\frac{f}{i} \times S \sin^{2} θ + (f + d) \sin θ$
(b)	$\frac{f}{i} \times S \cos^{2} θ + (f + d) \cos θ$

(d)	$\frac{f}{i} \times S c o t^{2} θ + (f + d) c o t θ$

When the line of sight is inclined and the staff is held vertically, the vertical distance is given by

(a)	$v = \frac{f}{i} s \frac{\sin 2 θ}{2} + (f + d) \sin θ$
(b)	$v = \frac{f}{i} s \frac{\sin 2 θ}{2} + (f + d) \cos θ$
(c)	$v = \frac{f}{i} s \frac{\cos 2 θ}{2} + (f + d) \cos θ$
(d)	$v = \frac{f}{i} s \frac{\cos 2 θ}{2} + (f + d) \sin θ$

When the line of sight is inclined but staff is held normal to the line of sight, the vertical distance is given by

(a)	$v = \frac{f}{i} s \sin θ + (f + d) \sin θ$
(b)	$v = \frac{f}{i} s \cos θ + (f + d) \cos θ$
(c)	$v = \frac{f}{i} s \sin θ + (f + d) \cos θ$
(d)	$v = \frac{f}{i} s \cos θ + (f + d) \sin θ$
