... 5) A dilation is when the figures points are multiplied by a scale factor to make the figure bigger or smaller. This is the only transformation that changes the figures size. Example – If triangle ABC has coordinates A(3, 4), B(1, 0) and C(-2, 3), what will the coordinates of the new figure be after ...

... In 2003 the State Pension was increased by 2% to £78.03. What was the State Pension before this increase? This is quite a difficult percentage question! 100% represents the total state pension before the increase. We know that 100% + 2% increase = 102% = £78.03 Use the diagram to calculate 100%, by ...

History of trigonometry

Early study of triangles can be traced to the 2nd millennium BC, in Egyptian mathematics (Rhind Mathematical Papyrus) and Babylonian mathematics.Systematic study of trigonometric functions began in Hellenistic mathematics, reaching India as part of Hellenistic astronomy. In Indian astronomy, the study of trigonometric functions flowered in the Gupta period, especially due to Aryabhata (6th century CE). During the Middle Ages, the study of trigonometry continued in Islamic mathematics, hence it was adopted as a separate subject in the Latin West beginning in the Renaissance with Regiomontanus.The development of modern trigonometry shifted during the western Age of Enlightenment, beginning with 17th-century mathematics (Isaac Newton and James Stirling) and reaching its modern form with Leonhard Euler (1748).
