After calculating the planar distance d between the two points as described above one must then adjust for the slope such that the actual distance D is defined by the following formula.
Find the length of CE.
One of the main application of trigonometry is to find the distance between two or more than two places or to find the height of the object or the angle subtended by any object at a given point without actually measuring the distance or heights or anglesTrigonometry is useful to astronomers navigators architects and surveyors etc. Let P x 1 y 1 and Q x 2 y 2 be two points on the Cartesian plane see picture below. If we have two points and we can easily substitute for and for. Tan th Opposite sideAdjacent side.
