If θ is the vertical angle of an inclined sight, δ is the angle of tilt of the staff, the error
If θ is the vertical angle of an inclined sight, δ is the angle of tilt of the staff, the error
if the line of sight is inclined, the vertical distance calculated will include the values of sin which is derived from the horizontal distance formula i.e., V = Ks \frac{sin2θ}{2} + C sin θ.
