The modern approach to Trigonometry also deals with how right triangles interact with circles, especially the Unit Circle, i.e., a circle of radius 1. Although the basic concepts are simple, the applications of Trigonometry are far reaching, from cutting the required angles in kitchen tiles to

Preview and Download !UNIT CIRCLE TRIGONOMETRY The Unit Circle is the circle centered at the origin with radius 1 unit (hence, the “unit” circle). The equation of this circle is xy22+ =1. A diagram of the unit circle is shown below: We have previously applied trigonometry to triangles that were drawn with no reference to any coordinate system.

TRIGONOMETRY - WORKSHEET WinAtSchool.org.uk If we only know the length of one side of the right angled triangle, but we know the angles of the corners, we can work out the lengths of the missing sides. We can do this by remembering: SOH, CAH, TOA. 𝑠𝑠𝑠(𝑥) = 𝑜𝑜𝑜𝑜𝑜𝑜𝑜𝑜 ℎ𝑦𝑜𝑜𝑜𝑜𝑦𝑦𝑜𝑜 𝑐𝑐𝑠(𝑥) = 𝑎𝑎𝑎𝑎𝑎𝑜𝑦𝑜 ℎ𝑦𝑜𝑜𝑜𝑜𝑦𝑦𝑜𝑜 𝑡𝑡(𝑠𝑥) = 𝑜𝑜𝑜𝑜𝑜𝑜𝑜𝑜 𝑎𝑎𝑎𝑎𝑎𝑜𝑦𝑜
