Skeletal surveys are also used with suspected non-accidental injury in children (CE guidelines state that 19 images of the child are taken.) These are reported on by a consultant paediatric radiologist and often copies are made.
Distance Formula and Pythagorean Theorem. The distance formula is derived from the Pythagorean theorem. To find the distance between two points (x 1 ,y 1) and (x 2 ,y 2), all that you need to do is use the coordinates of these ordered pairs and apply the formula pictured below. The distance formula is. $ \text{ Distance } = \sqrt{(x_2 -x_1)^2 + (y_2- y_1)^2} $.
Distance and Azimuths Between Two Sets of Coordinates. The terminal coordinates program may be used to find the coordinates on the Earth at some distance, given an azimuth and the starting coordinates. The shortest distance between two points on the surface of a sphere is an arc, not a line. (Try this with a string on a globe.) In addition, the azimuth looking from Point B to Point A will not be the converse (90 degrees minus the azimuth) of the azimuth looking from Point A to Point B.
