April
Calculate the inclined angle φ of a bend along a bended path.
January
Calculate the height of an object by measuring three angles of elevation only, from stations A, B and C on a straight level line to an inaccessible up-station D.
November
Calculate the coordinates of a distant point Tn, referencing measured angles and coordinates of four known points.
October
Calculate the height of an object from a baseline when its top and bottom is visible but not accessible from observation points. Case scenario when baseline AB on sloping ground and in line with object.
September
Calculate the height of an object from a baseline when its top and bottom is visible but not accessible from observation points. Case scenario when baseline AB is horizontal and in line with object.
August
Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB on sloping ground and not in line with object.
June
Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB on sloping ground and collinear with object.
May
Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB is level but not in line with object.
April
Calculate the height of an object from a baseline when its projected position to the ground is inaccessible. Case scenario when baseline AB is level and collinear with object.
March
Calculate the height of a building where the ground is sloping up or down from the observer.
