The great-circle distance orthodromic distance or spherical distance is the shortest distance between two points on the surface of a sphere measured along the surface of the sphere. As a pre-processing step the input array is sorted according to x coordinates. To have the student prove that the shortest distance between two points is a straight line and 2.
In general we do not need to measure from the 0 mark.
Well currently our table says that the shortest distance from a to b is and the same goes for the shortest distance from a to c. The distance between two points calculation formula is similar to the right triangle rule where the squared hypotenuse is equal to the sum of the squares of the other two sides. In a 3 dimensional plane the distance between points X 1 Y 1 Z 1 and X 2 Y 2 Z 2 is given by. In order to make this lesson more kinesthetic the teacher makes a right triangle on the floor using masking tape.
