Teachers can use appropriate technology to provide students with local-area examples of aerial photographs for calculations, for example, calculate the perimeter of a playing field or the area of an irregular-shaped field. Google Maps is an online resource that can be used to access maps and scaled aerial photographs, and to calculate distances on land. Online distance calculators and a ruler could also be used to determine the scale of a photograph. Aerial photographs of lakes or dams, combined with research about their depths, can be used to make volume calculations. Background information Almost all early civilisations used the shadow cast by a vertically positioned stick to observe the motion of the Sun and tell time. This instrument is now called a Gnomon, the Greek name of an L-shaped instrument used to draw a right angle. The foundations of trigonometry were laid as Babylonian, Greek, Hellenistic, Indian, and Arabic mathematicians investigated astronomical problems using numerical and geometric techniques, specifically the geometry of the circle. The most literal meaning of ‘trigonometry’ comes from the Greek words for and Trigonometry was established as a ‘triangle’ ‘measure’. distinct branch of mathematics during the 12th and 13th centuries. Herophilos (335–280 BC), a Greek physician and scientist was the first to publish information about heart rates. It was not until the invention of a stopwatch in 1707 that heart rates could be measured accurately.
